The present disclosure generally relates to systems and methods for propagating messages from consumers to one or more causes or events or locals, in association with payment transactions by the consumers.
This section provides background information related to the present disclosure which is not necessarily prior art.
Products (e.g., goods, services, etc.) are known to be offered for sale, and to be sold, by merchants. Consumers are known to purchase such products using payment accounts. Separately, users of social media may make posts of text messages and, optionally, images, which are served or displayed to other people via the Internet or similar networks. In order to enable the posts to be seen by a large audience, the poster may include “hashtags,” which are keywords that enable aggregation of social media posts pertaining to the same or similar topics. A user of social media may make posts supporting various organizations and/or events (charitable or otherwise) that they feel are important.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
Exemplary embodiments will now be described more fully with reference to the accompanying drawings. The description and specific examples included herein are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
At various organizations, causes, events, and other locations (broadly, all events), participants/attendants often make use of modern technology to access networks, contribute donations, or make other purchase transactions. Applications on the participants' mobile devices may enable the participants to select particular events and make desired transactions (e.g., donations, purchases, etc.) in connection with the events, or otherwise effect transactions for products being offered. Often, the participants may also like to share messages in support of the events with (or provide advertising to) other participants at the events, or with users of social media outside the events.
Systems and methods of the present disclosure enable the participants to make payment account transactions at the events (e.g., donations, product purchases, etc.), and to provide associated messages therewith for display at the events and/or on social media associated with the events (or otherwise). The messages are then shown on community message feeds for viewing by other participants at the events, and/or by social media supporters of the events. The message feeds may also include other related social media posts, news articles, and other related content (e.g., video content of other activities such as a sporting event, etc.). As such, the systems and methods herein generally enable participants to take an active part in the events, not just through the transactions, but also through customized messages spread throughout the events and social media sources. In addition, the participants performing the transactions may include hashtags to link their messages, as posts, to proper topics and, optionally, provide images to go with the messages.
It should be appreciated that the present disclosure is not limited in application to any particular events, but is generally applicable to multiple various different types of activities. For example, the systems and methods herein may enable users to effect donations at charitable events. In addition, the systems and methods herein may enable users to effect payment account transactions in exchange for advertising space on dynamic advertising boards or screens (e.g., at various events; at point of sale displays at airports, malls, hotels, vending machines, or the like (all broadly referred to as events herein); etc.). Other applications are also available, as will be apparent through the description herein.
The system 100 generally includes an event merchant 102, an acquirer 104, a payment network 106, and an issuer 108, each coupled to (and in communication with) network 110. The network 110 may include, without limitation, a local area network (LAN), a wide area network (WAN) (e.g., the Internet, etc.), a mobile network, a virtual network, and/or another suitable public and/or private network capable of supporting communication among two or more of the parts illustrated in
The event merchant 102 is generally associated with one or more organizations, causes, or events, etc. to which the event merchant 102 enables consumers (e.g., consumers 112a-c) to effect transactions in connection with the particular organizations, causes, or events. In turn, the consumers are then allowed to submit various messages for display at/by the event merchant 102 (or otherwise on social media). The event merchant 102 may provide physical locations to enable the consumers to make the transactions, and/or may provide information describing the process of making such transactions and providing such messages to the consumers.
It should be appreciated that, while only one event merchant 102 and three consumers 112a-c are illustrated in the
In some embodiments, the consumers 112a-c are able to fund transactions with the event merchant 102 via one or more payment accounts. Use of a payment account to fund such transactions may be authenticated by providing the correct information to the event merchant 102 (e.g., a primary account number (PAN), expiration date, account holder name, etc.). The account information may be manually provided by the consumers 112a-c or it may be provided through other means, such as by swiping a credit card through a magnetic card reader or presenting data for an electronic wallet via portable communication devices associated with the consumers 112a-c.
As an example, the consumer 112a, while at the event merchant 102, may initiate a transaction with the event merchant 102 for a monetary donation to the event merchant 102 (or to a donation-based organization associated with the event merchant 102), for example, by presenting a payment device associated with the consumer's payment account to the event merchant 102 (e.g., a credit card, a debit card, a fob, a smartcard, a web-based (or network based) e-wallet application, etc.). In turn, the event merchant 102 submits an authorization request (broadly, a transaction message) to the acquirer 104 (associated with the event merchant 102 and/or associated donation-based organization) for the transaction, along path A in
While the above transaction is described in connection with a donation to the event merchant 102, it should be appreciated that other transactions may be performed between the consumer 112a and the event merchant 102. For example, the consumer 112a may purchase products from the event merchant 102, may transact with the event merchant 102 in exchange for advertising, etc.
In any case, transaction data is generated, collected, and stored as part of the above interactions among the event merchant 102, the acquirer 104, the payment network 106, the issuer 108, and the consumers 112a-c (and included in the various transaction messages). The transaction data represents at least a plurality of transactions, for example, authorized transactions, cleared and/or settled transactions, attempted transactions, etc. The transaction data, in this exemplary embodiment, is stored at least by the payment network 106 (e.g., in a data structure associated with the payment network 106, etc.). Additionally, or alternatively, the event merchant 102, the acquirer 104 and/or the issuer 108 may store the transaction data, or part thereof, in a data structure, or transaction data may be transmitted between parts of system 100 as used or needed. The transaction data may include, for example, primary account numbers (PANs) for consumers involved in the transactions, tokens associated with the transactions, amounts of the transactions, an ID for the event merchant 102, transaction category codes, dates/times of the transactions, donation descriptions or identifiers, etc. It should be appreciated that more or less information related to transactions, as part of either authorization or clearing and/or settling, may be included in transaction records and stored within the system 100, at the event merchant 102, the acquirer 104, the payment network 106 and/or the issuer 108.
With continued reference to
In this exemplary embodiment, the communication devices 114a-b are portable communication devices, such as, for example, smartphones, tablets, laptops, etc. The communication devices 114a-b may include, or may be associated with, internet-based (or network-based) transaction applications (e.g., as stand-alone applications or in connection with e-wallet applications, etc.), or other applications that allow the consumers 112a-b to facilitate transactions to the event merchant 102, and which may include unique app identifiers or App IDs. In connection therewith, the communication devices 114a-b may be configured, by the applications, to further interact with a propagation engine 120 to deliver and receive information about the consumers' transactions with the event merchant 102 (and potentially other event merchants) and the like. This will be described in more detail hereinafter.
In addition, the display device 118 may be a device that is capable of displaying images, text, etc. and receiving display content via the network 110. While illustrated as a monitor in
Further, while one acquirer 104, one payment network 106, and one issuer 108 are illustrated in
In the exemplary embodiment of
Referring to

In the exemplary embodiment, the computing device 200 also includes a presentation unit 206 that is coupled to (and in communication with) the processor 202 (however, it should be appreciated that the computing device 200 could include output devices other than the presentation unit 206, etc.). The presentation unit 206 outputs information (e.g., consumer messages, etc.), visually, for example, to a user of the computing device 200 such as the consumers 112a-c in the system 100; users associated with one or more of the event merchant 102, the acquirer 104, the payment network 106, and the issuer 108; etc. It should be further appreciated that various interfaces (e.g., as defined by internet-based (or network-based) applications, websites, etc.) may be displayed at computing device 200, and in particular at presentation unit 206, to display certain information. The presentation unit 206 may include, without limitation, a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, an “electronic ink” display, speakers, etc. In some embodiments, presentation unit 206 includes multiple devices. In addition, the computing device 200 includes an input device 208 that receives inputs from the user (i.e., user inputs) such as, for example, transaction information, messages, etc. The input device 208 may include a single input device or multiple input devices. The input device 208 is coupled to (and in communication with) the processor 202 and may include, for example, one or more of a keyboard, a pointing device, a mouse, a stylus, a touch sensitive panel (e.g., a touch pad or a touch screen, etc.), another computing device, and/or an audio input device. Further, in various exemplary embodiments, a touch screen, such as that included in a tablet, a smartphone, or similar device, behaves as both a presentation unit and an input device.
Further, the illustrated computing device 200 also includes a network interface 210 coupled to (and in communication with) the processor 202 and the memory 204. The network interface 210 may include, without limitation, a wired network adapter, a wireless network adapter, a mobile network adapter, or other device capable of communicating to one or more different networks, including the network 110. Further, in some exemplary embodiments, the computing device 200 includes the processor 202 and one or more network interfaces incorporated into or with the processor 202.
Referring again to
With that said, in connection with the exemplary transaction described above, the propagation engine 120 is configured to receive a message request relating to the transaction performed by the consumer 112a at the event merchant 102 (e.g., from the event merchant 102, etc.). The message request may be in the form of a data structure that includes payment account information for the consumer 112a and corresponding message information provided by the consumer 112a. The propagation engine 120 may be configured to further store the message request (e.g., in memory 204, etc.), to create and maintain consumer message content feeds, and to cause the corresponding transaction performed by the consumer 112a to be processed. In alternative embodiments, message requests may be sent to the propagation engine 120 from other consumers and other computing devices (e.g., communication device 114b, etc.). As an example, consumer 112a at the event merchant 102 may create the payment account transaction to the event merchant 102 using the communication device 114a as an enabled payment device. The communication device 114a may be configured by an application to then deliver a message request, including the created transaction, to the propagation engine 120, via the network 110.
The message request sent to the propagation engine 120, by the event merchant 102, for example, includes transaction information such as payment information for processing the transaction and message information, created by the consumer 112a, for propagation and display of the consumer's desired message. Upon receipt, the propagation engine 120 delivers the payment information, which may include a payment token for identifying and/or authenticating the transaction, to the payment network 106 for processing (e.g., via the acquirer 104 associated with the event merchant 102, etc.) as described above (and generally consistent with path A in
The propagation engine 120 uses the message information created by the consumer 112a to create or add to one or more message feeds. A message feed may include one or more messages from consumers (including the consumer 112a), and it may also include other content associated with the cause(s) of the feed. For instance, a donation message feed associated with a charity event for finding a cure for cancer may include social media posts and/or news articles associated with the charity, recent cancer research, a famous philanthropist's contribution to a cancer cure, etc. Alternatively, an advertising message feed associated with a display at an airport may include advertising content created by the consumer 112a, in connection with the transaction at the event merchant 102 (which entails paying for the advertising). In any case, the propagation engine 120 may access the Internet (or other network) in order to find message feed content beyond the messages received from consumers to display. In order to find message feed content, the propagation engine 120 may execute keyword searches at various social media sources (e.g., Twitter, Facebook, Pinterest, Instagram, etc.), news sources, as well as keyword searches using social media hashtags, other handles, and/or RSS/Atom feeds from related websites.
The message content provided by the consumer 112a in the above example may include a name of the consumer 112a, an amount of the transaction (e.g., when the transaction includes a donation transaction, etc.), and a message provided by the consumer 112a. The consumer 112a may include the message with his/her transaction with the goal of the message being displayed on a particular message feed associated with the message and/or the event merchant 102, or on a particular message feed identified by the consumer 112a. The message may also include an image chosen by the consumer 112a, as well as hashtags to link the message to various social media topics.
The propagation engine 120 may maintain multiple message feeds, which includes updating the content of the message feeds as content is received and removing content that has grown stale (content that has been on the feed for longer than a defined time period, etc.). While message feeds may include repeated content, it should be understood that it is advantageous to include current content in the message feeds to capture the interest of viewers of the message feed. The time period for “staleness” of content may be defined within the propagation engine 120, and may include periods such as one hour, three hours, one day, one week, etc.
With continued reference to
The computing devices may request the current message feed or a message feed for a particular timeframe (e.g., the message feed content from the past one hour, all message feed content up to the present, etc.). In some embodiments, the computing devices may display message feed content at an event, to an audience at the event, along with other content such as a streaming video of the event (e.g., such as at a baseball game, a football game, etc.). Or, the computing devices may display message feed content individually to consumers, such as consumer 112b via communication device 114b. The content of a consumer's individual feed may be determined based on preferences of the consumer, history of the consumer's participation at events, the consumer's individual location (e.g., a particular room at an event, a particular section or seat in an arena, a particular neighborhood, a particular mall, etc.). It should be understood that the computing devices send requests for message feeds associated with the event or event merchant 102 frequently in order to provide observing consumers/audience members with the most up-to-date content. The consumer could send more granular location data, such as a seat at a game, and a message feed could be filtered by location. For example, there could be a feed from courtside at a basketball game, a feed from outside the stadium, and/or a feed from fans at their homes.
In some embodiments, the propagation engine 120 may include or provide a dashboard application, to the event merchant 102, that displays incoming transactions from consumers (e.g., donations, product purchases, etc.) in real-time (including from the consumer 112a). The dashboard may display transaction amounts along with associated messages as they arrive at the propagation engine 120 and are processed. The dashboard may also display attached images. The dashboard enables the event merchant 102 to monitor transaction and message traffic through the propagation engine 120. While monitoring traffic through the propagation engine 120, the event merchant 102 may approve and/or disapprove content prior to it being added to a message feed. The event merchant 102 may disapprove content due to profanity, offensiveness, bad taste, or the like. Additionally, the dashboard may enable the event merchant 102 to monitor transaction amounts raised (e.g., donation amounts when the transactions involve donation transactions, etc.), as well as other statistical information associated with an event.
At 302 in the method 300, a mobile application may be executed on a computing device, such as communication device 114a, to provide consumer 112a with a list of nearby events, including their associated event merchants, which may be accepting messages (and associated transactions). As previously described, the events may include, without limitation, charity events at which the consumer 112a can make donations and provide associated donation messages, sporting events at which the consumer 112a can provide messages for display at the events for a charge, retail events at which the consumer 112a can provide a message upon purchasing a product, advertising events (e.g., at a mall, at an airport, etc.) at which the consumer 112a can provide an advertising message to be displayed at particular advertising media for a charge, etc.
The list of events may be generated by the mobile application using Global Positioning System (GPS) technology of the computing device, along with known locations of the nearby events. In addition, the list of events may be organized by types of the events, as desired, and may be searchable by the consumer 112a. The events may be provided to the consumer 112a on a screen, or other similar presentation unit (e.g., presentation unit 206, etc.), of the communication device 114a. The entries of the list may include information about the events, including the name of each event, the distance of the event's location from the communication device 114a, based on GPS technology, a description of the event, contact information for the event, etc. The mobile application is configured to enable the consumer 112a to select an event to which he/she would like to interact. In alternative embodiments, the list of events may be based on other factors, rather than location, such as a keyword search by the consumer 112a, the consumer's preferences, the consumer's transaction history, etc.
In turn, the mobile application receives information from the consumer 112a, at 304, regarding a desired event to which the consumer 112a wishes to interact. The event information may include a selection of one of the events from the list or it may include a particular event provided by the consumer 112a. In either case, the event information generally includes an indicator of the selected event, an amount associated with providing a message at the selected event, a message to include with the corresponding payment account transaction, a picture to include with the transaction, hashtags to link to the message, etc. The mobile application also receives payment information from the consumer 112a, including a payment account number, other payment account credentials, etc. The event information and payment information are received by the mobile application through an interface, such as via a keyboard, touchscreen, or other input device (e.g., input device 208, etc.), as described above. Further, in various embodiments, the payment information may be received by the mobile application via an electronic wallet.
When the event information and payment information are collected, the mobile application sends the information to the propagation engine 120, at 306, as a message request (either directly, or via the event merchant associated with the selected event). The information may be sent via a network, such as network 110. The mobile application may be configured to send information to the particular propagation engine 120, or there may be more than one propagation engine and the mobile application may send the information to a propagation engine based on the selected event, event information, or payment information.
At 308, the propagation engine 120 receives the message request, and at 310, the propagation engine 120 extracts the payment information and the event message information from the received request. The payment information, which may include a payment token used to identify the associated transaction, is delivered to a payment processing system (e.g., including the acquirer 104, the payment network 106, and the issuer 108, etc.), while the event message information is retained by the propagation engine 120. In some embodiments, the payment token is generated by the mobile application at the consumer's communication device 112a, or it may be generated by the propagation engine 120 communicating with the payment network 106 based on the received payment information. The generated payment token is used for secured data transmittal for processing payment of the transaction.
The payment processing system receives the payment information, at 312, and processes the payment account transaction, at 314, to the user's payment account in the manner described above for system 100 (e.g., along path A in
With continued reference to
The message feed for the event may include a variety of content pertaining to the event. For instance, a message feed may include messages associated with the event from other consumers at the event, and it may also include social media posts, news articles, live feeds, etc. which are associated with the event, as described above. The propagation engine 120 may populate a message feed with content which has been tagged, or “hash-tagged,” with keywords that pertain to the event. Alternatively or additionally, the propagation engine 120 may include content which contains keywords associated with the event.
The content of the message feed may be limited to a recent timeframe. For instance, content may be added to a message feed if it was posted and/or sent to the propagation engine 120 later than a defined time threshold (e.g., one day ago, three days ago, one week ago, one hour ago, etc.). The message feed content may be limited in other ways, such as requiring a minimum transaction amount (e.g., a minimum donation, a minimum purchase, etc.), or requiring an image to be included with a message. Messages, social media posts, and other message feed content may be filtered for certain words, phrases, images, etc.
Separately in the method 300, a television application, which may be executed on a computing device, such as the display device 118, is configured to request a current message feed from the propagation engine 120, at 320. The request may include a computing device identifier or television application identifier, as well as information identifying the message feed being requested. In some embodiments, the television application requests all current message feeds. The request may be delivered to the propagation engine 120 via network 110.
Upon receiving the message feed request, at 322, the propagation engine 120 sends the current message feed associated with the request, at 324, to the television application. In connection therewith, the propagation engine 120 may process the message feed request upon reception, which may include confirming that the requesting television application is authorized to access the requested message feed.
At 326, the television application receives the requested current message feed and displays the message feed, at 328. Displaying the message feed may take place over a period of time, with the displayed content changing at intervals throughout the time period. For instance, if the message feed includes six different messages with images, the message feed may display each message and image for five seconds before moving on to the next message and image. Displaying the message feed in this manner would require thirty seconds. In addition, the message feed may be displayed on loop, so that, when the feed is finished, it starts over from the beginning. In alternative embodiments, the content of the message feed may be displayed in a random or pseudo-random order. In some embodiments, messages may be streamed in motion across the display of the television application, and related images may be displayed when the associated message is on screen or mostly on screen. The television application may store received feeds until they can be displayed.
In some embodiments, the mobile application may also request a current message feed, at 330, for example, relating to an event selection from the consumer 112a at 304, etc., and may receive a current message feed, at 332, and display the current message feed, at 334. The process of the mobile application may function in a substantially similar way to the television application described above.
In the embodiment of
The event selection screen 402 also includes a view map button 408 that may enable the consumer 112a to view the listed events 406 on a map at the consumer's communication device 114a. Interacting with the view map button 408 may cause a map (not shown) to be displayed on the interface showing the location of each of the listed events 406 as well as the current location of the communication device 114a on which the user interface 400 is being displayed. The map may enhance the consumer's ability to find a particular one of the events 406 that he/she wants to attend.
The event selection screen 402 further includes an event details button 410. The event details button 410 may cause the display of additional details about a selected one of the events 406. The event details may include a detailed description of the event, an address and other contact information for the event, etc.
Finally, the event selection screen 402 includes a select event button 412. When the consumer 112a has highlighted one of the events 406 with which he/she would like to interact, he/she may actuate the select event button 412 to display the event creation screen 404.
The event creation screen 404 includes a message section 414 which enables the consumer 112a to provide a personalized message to go along with a transaction to the event. This message may include text as well as hashtags, which link the message to related topics on social media. In
In addition at the event creation screen 404, an attach image button 418 enables the consumer 112a to include an image with the message, such that the image will be displayed when the message is displayed on a message feed, as described above. Interacting with the attached image button 418 may access images stored on the communication device 114a and/or enable the consumer 112a to take a photo with a camera of the communication device 114a.
When the consumer 112a has completed information entry for the transaction, he/she may interact with button 420 to finalize the transaction and the message. The button 420 causes the created transaction and message to be delivered to the propagation server 120, again as described above.
In view of the above, the systems and methods herein may permit propagation of messages associated with payment account transactions. In particular, users may generate transactions at events and include personalized messages with the transactions that are then propagated, by a propagation engine, for display.
