In general, embodiments of the invention relate to methods, systems and computer program products for providing audio messages relating to financial transactions.
Consumers today have a variety of digital tools available to them which allow them to review and manage their financial transaction data. For example, transaction summaries are often available in online banking accounts accessible via mobile communication devices. In other instances, consumers may receive e-mail or text messages containing transaction data from recent transactions. Unfortunately, visually impaired individuals are often unable to readily take advantage of such tools. Such individuals may use screen readers, magnification software, and other accessible computer technology in order to try to obtain value from products and functionality that were designed and implemented to be utilized by consumers without visual impairments. While visually impaired consumers may be able to eventually comprehend the financial transaction content presented visually by the various tools of the prior art through application of specially-designed tools for the visually impaired, this is an inefficient and imprecise manner of obtaining the relevant information that is also ill-suited for translation into the handheld computing field (as accessible technology for the visually impaired is often designed for use with personal computers such as laptops and desktops). Therefore, there remains a need for an improved system for providing visually-impaired consumers with the ability to readily review and manage their financial transactions.

As further illustrated in
With reference now to
A shown in block 202 of
During enrollment of the consumer 102 into the financial transaction audio messaging program, the consumer 102 may indicate her preferences as to how, when, and where the audio messages should be provided to the consumer 102. Thus, in some embodiments, the consumer 102 not only indicates that she would like to receive audio messages summarizing her financial transactions, but also provides information relating to how she would like to receive such audio messages, including by voicemail, automated telephone call, email with audio file attachment or file attachment containing audio among other media (such as video), Multimedia Messaging Service messages containing audio, or other audio messaging format. It should be understood that as used herein “audio messages” and “audio messaging” means the communication of content that includes an audio component. Thus, “audio messages” are not limited to audio recordings and content alone, but may also include audio/video recordings and other multimedia content. In some embodiments, the consumer 102 may indicate that she does not wish the audio messages to be transmitted to her, but rather posted within her account on the online banking platform 126. In other embodiments, the consumer 102 may indicate that she would like the audio messages both sent to her via one of the methods listed above or via another known method of sending audio content to a remote recipient and would like the audio messages posted to her account within the online banking platform 126. As part of the enrollment process, according to some embodiments, the consumer 102 may provide a telephone number, email address, or other contact information or online account information that will enable the bank to send the audio messages as requested.
In addition to communicating her preference regarding how and where the audio messages should be provided or transmitted, in some embodiments, the consumer 102 also indicates her preference as to how often to receive such audio messages. For example, the consumer 102 may wish to receive the audio message corresponding to a particular transaction immediately after the bank becomes aware that a transaction affecting her account has been made. Alternatively, the consumer 102 may wish to only receive summaries of her transactions on a periodic basis, for example once a day, once every two days, or once a week. In such an instance, the audio message transmitted or otherwise made available to the consumer 102 would include the transaction information for multiple transactions, rather than a single transaction. Furthermore, according to some embodiments, the consumer 102 may only wish to receive audio messages for certain types of transactions, such as withdrawals, deposits, or purchases. In some embodiments, the consumer 102 may identify a particular vendor, or a particular type of vendor, for example, clothing stores, and indicate that she would only like to receive audio messages for transactions conducted with that vendor or that type of vendor. The consumer 102 may also, in some embodiments, have selected to only receive audio messages summarizing the financial transactions affecting an account if the financial transactions involve the transfer of money over a particular threshold amount, if the financial transactions are made in particular geographic locations or if the financial transactions are made using one bank card out of multiple bank cards associated with the account. During enrollment, the consumer 102 may also determine what information will be included in the audio message, for example, the date of the transaction, the amount of the transaction, whether the transaction was a purchase, a withdrawal, a deposit, etc., and the identity of the other party involved in the transaction, including the address of such party. Indeed, it should be appreciated that there are countless ways in which the bank may wish to structure the ability of the consumer 102 to provide her preferences regarding the financial transaction audio messaging program. Thus, the consumer 102 completes enrollment by indicating her preference to receive financial transaction audio messages and her preferences regarding how and how often such audio messages should be communicated to her. Referring now to
As represented by block 204 in
In some embodiments, the payment between the consumer 102 and the third party may be made by credit card, debit card, check, ACH transfer, or other mutually-accepted payment mechanism and effected through the use of the POT computer system 130. As used herein, the term “bank card” refers to a debit card, credit card, or any other device that is used by a consumer to effectuate a financial transaction. As used herein, the term “bank card” is not limited to cards issued by banks and, instead, also includes cards and other devices issued by other financial institutions or their agents. As used herein, the term “bank account” refers to a debit account, credit account, demand deposit account, money market account, savings account, or any other type of account that may be involved in a financial transaction. In general, and in accordance with embodiments of the present invention, the POT computer system 130 processes a bank card, check or ACH transfer payment by utilizing the payment processing application 136 and communicating with the bank computer system 120 using the communication device 131 to get authorization for and/or clearance of the payment.
With regard to the nature of the POT computer system 130, the POT computer system 130 may be any type of computer system used for processing financial transactions and may be operated by or on behalf of any entity or multiple entities, including the consumer 102 or the bank. Furthermore, the POT computer system 130 may be located at the point-of-transaction, or may be in a remote location. For example, if the consumer 102 engages in a financial transaction by purchasing goods from a vendor using her debit card, the POT computer system 130 would generally include the computer system employed by the vendor to process the debit card payment, including, for example, the computer system of the checkout register and debit card kiosk and the computer systems of the vendor's banking institution and any intermediary financial institution. Alternatively, and for the purposes of example only, if the consumer receives a payment from a third party by ACH transfer, the POT computer system 130 would generally include the computer systems employed to transfer the funds. In such a scenario, the POT computer system 130 may be owned and operated by the bank and may even be integrated with the bank computer system 120. As another example, the consumer 102 may be equipped to receive bank card payments, in which case the POT computer system 130 used to process such transactions may be owned, operated, or otherwise employed by the consumer 102. In yet another example, the consumer 102 may make a purchase online or through a mobile device system using the consumer's mobile phone or other personal computing device. In such an embodiment, the consumer's mobile phone or other personal computing device may perform the functions of bank card and bank card terminal. The mobile phone or other personal computing device may also then perform the functions of the consumer computer system 110. In other words, the consumer's mobile phone or other personal computing device may serve as both the consumer computer system 110 and a portion of the POT computer system 130, and a vendor server interacting with the consumer's mobile phone or other computing device over a network may serve as another portion of the POT computer system 130. Therefore, it will be understood that, while the POT computer system 130 is illustrated in
According to different embodiments of the invention, the financial transaction itself may take on forms different from a credit card, debit card, check, or ACH transfer payment involving the consumer 102 and a third party. For example, in one embodiment, the financial transaction is a transfer of funds between multiple accounts held by the consumer 102. In other embodiments, the financial transaction is a withdrawal from or a deposit to an account of the consumer 102, whether by ATM machine, teller, or otherwise. In each of the foregoing examples, because the bank may be the entity processing the transfer, withdrawal, deposit, or clearance of the check from the account of the consumer 102, the POT computer system 130 may be operated by or on behalf of the bank. Therefore, as discussed above, it may be the case that the POT computer system 130 is not distinct from the bank computer system 120 and that these two computer systems are one and the same. As a general note, the examples of financial transactions provided herein should not limit the type of financial transaction that may be the subject of the present invention, and, indeed, any financial transaction that causes an entry to be made by the bank (using the bank computer system 120) in an account of the consumer 102 is suitable for the methods of embodiments of the present invention, whether such entry is a debit, credit, or otherwise.
As described above, where the financial transaction involving the consumer 102 involves the debiting or crediting of a consumer's bank account, the financial transaction is processed by the POT computer system 130 and the bank computer system 120 working in communication with one another. More specifically, the POT computer system 130 uses the communication device 131 and the payment processing application 136 to communicate to the bank computer system 120 information regarding the transaction to be carried out, including the amount of money at issue and the origin and destination of that money, as well as information identifying the consumer 102 and/or the particular account belonging to the consumer 102 that is affected by the transaction. The bank computer system 120 uses the information communicated from the POT computer system 130 to process the financial transaction within the bank. Essentially, the information communicated by the POT computer system 130 includes instructions to the bank computer system 120 to debit, credit, or otherwise adjust a particular account of the consumer 102. Therefore, according to some embodiments of the invention and as represented by block 304 in
Once the bank has processed the financial transaction within the bank as described above, in accordance with some embodiments of the invention and as represented by block 306, the bank then determines whether the consumer 102 has previously enrolled in the financial transaction audio messaging program for the account affected by the financial transaction or otherwise stated a preference that she receive audio messages from the bank containing financial transaction information. This information is stored, for example, in the memory device 123 of the bank computer system 120 in relation to the account of the consumer 102 so that the bank could locate the information whenever a transaction affecting that account is processed. More particularly, the account management application 125, upon receiving an indication from the POT computer system 130 that there is a transaction affecting the account of the consumer 102, records the details of the transaction in the account and instructs the processing device 122 to determine whether there is information stored in the memory device 123 that instructs the bank to transmit or otherwise make available to the consumer 102 an audio message or a portion of an audio message corresponding to the financial transaction. In the event the consumer 102 has stated a preference of receiving audio messages, the banking computer system 120, according to some embodiments, will also determine how to transmit or otherwise make available to the consumer 102 an audio message relating to the financial transaction communicated by the POT computer system 130. Such a determination may be made at the same time or after the bank determines that the consumer 102 has stated a preference to receive audio messages.
Thus, in some embodiments, and as represented by block 308, the bank computer system 120 will query the preference information stored in the memory device 123 in relation to the account of the consumer 102 and will determine if audio messages should be immediately sent to the consumer 102. In the event the consumer 102 indicated a preference to receive the audio messages as soon as possible after the transaction is attributed to the account, or if the default messaging option in the financial transaction audio messaging program is to have the audio messages immediately sent, the bank computer system 120 automatically generates an audio message summarizing the financial transaction and transmits the message to the consumer 102. In particular, as represented by block 310, the bank computer system 120 retrieves from the memory device 123 the telephone number, email address, or other contact information for the consumer 102 and utilizes the electronic communications application 127 to transmit, via the communication device 121, an audio message to such telephone number, email address, etc. According to different embodiments, the message may take the form of an audio attachment, an MMS having an audio component, an automated telephone call, or other audio messaging format. In some embodiments, the message is encrypted for security purposes. In such embodiments and as described further below, the message may be decrypted after receipt by the consumer computer system 110 by the electronic communications application 117 or other application stored on the memory device 113.
If the consumer 102 has not indicated a preference to receive audio messages immediately and/or if sending audio messages immediately is not the default mode of the program, as represented by block 312, the bank computer systems 120 will determine if it should wait to send an audio message containing certain information relating to the financial transaction. For example, the consumer 102 may have indicated a preference to only receive audio messages when a certain number of transactions, such as ten, have been processed by the bank computer system 120 that affect the account of the consumer 102. Or the consumer 102 may have indicated a preference to only receive financial transaction audio messages once a day, once a week, or some other time period. In such instances, as represented by block 314, the bank computer system 120 transmits an audio message containing a summary of the financial transaction at the predetermined time or when the predetermined number of transactions has been made. The bank computer system 120 may generate the audio message summarizing the transaction immediately and hold it for transmission at a later time with other audio messages corresponding to financial transactions made during the relevant time period. However, in some embodiments, the message that is eventually sent is a master message that contains financial transaction information corresponding to multiple transactions. Thus, the bank computer system 120 is configured to identify the financial transaction that will be the subject of a future audio message, and once the predefined number of transactions have been made or the predefined period of time has lapsed, the bank computer system 120 generates a master audio message containing information summarizing all financial transactions made during the relevant period affecting the account of the consume 102 that should be sent to the consumer 102 according to the stored preference information. The bank computer system 120 uses the electronic communications application 127 to transmit the message(s) to the consumer at the telephone number, email address, or other address/number stored in the memory device 123.
As discussed above, the information contained in the audio message may include any information concerning the financial transaction and/or the account of the consumer 102 as requested by the consumer 102, for example, the date, location, type, and amount of the transaction, information about any other entities involved in the transaction, and the remaining balance in the account, etc. Therefore, according to some embodiments, the bank computer system 120 queries the memory device 123 to determine whether or not audio messages should be sent to the consumer 102, where they should be sent, how often they should be sent, and what they should contain. All of this information may be provided by the consumer 102 as preference information during enrollment or may be selected by the bank as a default setting for the financial transaction audio messaging program.
In the event audio messages are not to be transmitted to the consumer 102 at all, i.e. the preference information stored in the memory device 123 specifies that audio messages should not be send immediately nor held and sent in batches, the bank may still provide audio messages summarizing financial transactions for access by the consumer 102 via the online banking platform 126. As represented by block 316, the bank computer system 120 will, upon determining that the consumer 102 wishes to have the benefit of audio messages but does not wish to receive them at a personal telephone number, email account, or other location, post to the account of the consumer 102 accessible through the online banking platform 126, financial transaction audio messages. These messages may be posted such that one message corresponds to one financial transaction or, as with the batches previously discussed, the consumer 102 may be able to open, via the online banking platform 126, one audio file that contains summaries of multiple financial transactions. For example, the user may access a single audio message that contains summaries of all financial transactions made during the current bank account statement period. As with the other methods of delivery of audio messages, the content and form of the audio message may be highly configurable by the bank computer system 120 according to the preferences of the consumer 102. It should also be understood that the consumer 102 may elect more than one method of receiving audio messages. For example, the consumer 102 may wish to receive immediate audio messages via automated telephone call following each transaction affecting a particular account as well as be able to access a master audio message containing the transaction information for all transactions made during a certain time period via the online banking platform 126. Embodiments of the present invention may provide for providing financial transaction audio messages to consumers in one or more of the ways discussed herein.
With reference again to
Where the POT computer system 130 and the bank computer system 120 are able to process a payment or other transaction in real-time or near-real-time, which is the case for many of the financial transactions that are the subject of embodiments of this invention, and where the consumer has elected to have audio messages transmitted to the consumer 102 as soon as transactions are processed and attributed to the account, the consumer 102 may receive the audio message at the point-of-transaction or very shortly after leaving the point-of-transaction. This advantageously allows the consumer 102 to quickly identify transactions that do not belong to her so that a responsive action, such as putting a hold on or canceling a particular bank card, may be taken before further fraudulent charges are made. Therefore, in some embodiments and as represented by block 208, the consumer 102 will determine whether the transaction described in the message was initiated by her or a person authorized to make transactions involving her account. In the event that the transaction was not initiated by the consumer 102 or a person authorized by the consumer 102, according to some embodiments and as represented by block 210, the consumer 102 may contact the bank to report the unauthorized transaction.
In addition to allowing detection of unauthorized use of a bank card or account, embodiments of the present invention also allow consumers to determine whether they have been overcharged during transactions. This is particularly advantageous for persons with visual impairments because such individuals are especially susceptible to fraud by vendors. Visually impaired persons must often rely on the word of the cashier or salesperson that they are being charged the appropriate amount. Thus, embodiments of the present invention provide a method of communicating to a consumer 102 the actual amount charged to the account of the consumer 102. The consumer 102 listens to the audio message and, as represented by block 212, determines whether the amount of the transaction is accurate. In the event the consumer 102 recognizes that a transaction was made, but the amount of the transaction is inaccurate, then, according to block 214, the consumer 102 can take action to report the fraudulent or incorrect transaction. In one embodiment, the consumer 102 can use the consumer computer system 110 to reply to the audio message with a notification that the transaction is unauthorized and/or the amount of the transaction is incorrect.
In some embodiments, the consumer 102 may utilize the messages for purposes other than to determine whether an inaccurate or unauthorized transaction has been processed to the account of the consumer 102. For example, according to some embodiments, and as represented by block 212, the consumer 102 may store the audio message in the memory device 113 of the consumer computer system 110, or, in the event the audio message was accessed via the online banking platform 126 rather than received by the communication device 111 of the consumer computer system 110, then the consumer 102 may elect to continue to store the audio message in the memory device 123 of the bank computer system 120 such that it appears in the account of the consumer 102 accessible via the online banking platform 126. As represented by block 216, the consumer 102 may access the audio message from time to time thereafter, whether stored in the memory device 113 of the consumer computer system 110 or the memory device 123 of the bank computer system 120, in order to reconcile and balance her account.
While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention not be limited to the specific constructions and arrangements shown and described, since various other changes, combinations, omissions, modifications and substitutions, in addition to those set forth in the above paragraphs, are possible. Those skilled in the art will appreciate that various adaptations and modifications of the just described embodiments can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
