The present technology is generally related to the field of consumer-operated kiosks and, more particularly, to access security for such kiosks and other commercial enclosures.
There are numerous types of consumer-operated vending and service machines in use today, including food and drink vending machines, coin counting kiosks, DVD rental kiosks, etc. Various embodiments of consumer-operated kiosks are disclosed in, for example: U.S. Pat. Nos. 5,620,079, 6,494,776, 7,584,869, 7,653,599, 7,748,619, 7,815,071, and 7,865,432; and U.S. patent application Ser. Nos. 12/758,677, 12/806,531, 61/364,360 and 61/409,050; each of which is incorporated herein in its entirety by reference.
Many consumer-operated kiosks, vending machines, and other commercial sales/service/rental machines include a sturdy housing or enclosure that protects inventory, money, and/or internal workings from unauthorized access or theft. Service personnel, however, must be able to access such machines to restock inventory or consumables, remove money, perform maintenance and repairs, and perform other functions. For this reason, most kiosks include a lockable access door that requires a service personnel key to open. In addition, some doors can include a mechanical switch for recording door opening and closing times. These times can be compared to service personnel logs to ensure that only authorized personnel had access to the machine at all times.
One downside of mechanical door switches, however, is that they can often be easily bypassed or otherwise disabled without detection. Even some magnetic switches can be relatively easy to compromise with an appropriately-placed refrigerator magnet. Accordingly, it would be advantageous to provide a relatively simple access monitoring system that could not be easily defeated.
The following disclosure describes various embodiments of systems and associated methods for monitoring, recording, and/or controlling access to consumer-operated kiosks and other enclosures. In one embodiment of the present invention, a consumer-operated kiosk (e.g., a consumer coin counting machine, prepaid card dispensing/reloading machine, DVD rental machine, etc.) includes an access door having a digital “smart switch” that utilizes wireless technology to determine door status (e.g., whether the door is opened or closed). In this embodiment, the digital door switch includes a digital identifier, such as a radio frequency identification (RFID) transponder or “tag” mounted to one of the machine enclosure or the door, and a wireless reader, such as an RFID reader, mounted to the other of the enclosure or the door. When the door is closed, the identifier moves into proximity of the reader and the reader detects the presence of the identifier. The presence of the identifier indicates that the door is in the closed position. Conversely, when the door is opened the identifier moves away from the reader so that the reader can no longer detect the presence of the identifier. The absence of the identifier indicates that the door is open.
In some embodiments, the reader can communicate door status information to a kiosk computer or other processing device, which can in turn record, for example, when the door is opened, when the door is closed, and how long the door remained open. Moreover, in some embodiments this access information can be uploaded to a computer located remotely from the kiosk (such as a computer located at a kiosk operating center) that may be connected to a network of similar kiosks. The access information for a particular kiosk can then be compared to service personnel access logs for that machine to ensure that only authorized persons had access to the kiosk at all times. Moreover, in the event that money or other items are found to be missing from a particular kiosk, the recorded access times can be used to ascertain who had access to the machine during the time period in question.
Some aspects of the present invention are described below in the general context of computer-executable instructions, such as routines executed by a general-purpose data processing device, e.g., a personal computer, RFID reader controller, server computer, and/or wireless device. Those skilled in the relevant art will appreciate, however, that some aspects of the invention can be practiced with other communications, data processing, or computer system configurations, including, for example: Internet appliances, hand-held devices (including personal digital assistants (PDAs)), wearable computers, all manner of cellular or mobile phones (including Voice over IP (VoIP) phones), dumb terminals, media players, multi-processor systems, microprocessor-based or programmable consumer electronics, set-top boxes, network PCs, mini-computers, mainframe computers, and the like. Indeed, the terms “computer,” “controller,” “server,” “host,” “host system,” and the like are generally used interchangeably herein, and generally refer to any of the above devices and systems, as well as any data processor.
Aspects of the invention can also be embodied in a special purpose computer or data processor that is specifically programmed, configured, or constructed to perform one or more of the computer-executable instructions explained in detail herein. While some aspects of the invention, such as certain functions, may be described as being performed exclusively on a single device, the invention can also be practiced in distributed environments where functions or modules are shared among disparate processing devices which are linked through a communications network, such as a Local Area Network (LAN), Wide Area Network (WAN), or the Internet. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
Some aspects of the invention may also be stored or distributed on tangible computer-readable media, including magnetically or optically readable computer discs, hard-wired or preprogrammed chips (e.g., EEPROM semiconductor chips), nanotechnology memory, biological memory, or other data storage media. Alternatively, computer implemented instructions, data structures, screen displays, and other data under aspects of the invention may be distributed over the Internet or over other networks (including wireless networks), on a propagated signal on a propagation medium (e.g., an electromagnetic wave(s), a sound wave, etc.) over a period of time, or they may be provided on any analog or digital network (packet switched, circuit switched, or other scheme).
Certain details are set forth in the following description and in
The terminology used below is to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain examples of embodiments of the technology. Indeed, certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this detailed description.
The accompanying Figures depict embodiments of the present technology and are not intended to be limiting of its scope. The sizes of various depicted elements are not necessarily drawn to scale and these various elements may be arbitrarily enlarged to improve legibility. Component details may be abstracted in the Figures to exclude details such as position of components and certain precise connections between such components when such details are unnecessary for a complete understanding of how to make and use the invention.
Many of the details, dimensions, angles and other features shown in the Figures are merely illustrative of particular embodiments of the disclosure. Accordingly, other embodiments can have other details, dimensions, angles and features without departing from the spirit or scope of the present invention. In addition, those of ordinary skill in the art will appreciate that further embodiments of the invention can be practiced without several of the details described below.
In the Figures, identical reference numbers identify identical, or at least generally similar, elements. To facilitate the discussion of any particular element, the most significant digit or digits of any reference number refers to the Figure in which that element is first introduced. For example, element 110 is first introduced and discussed with reference to
In the illustrated embodiment, the consumer-operated kiosk 100 includes an external housing, such as an enclosure 102 having a hinged access panel, such as a front door 104. The door 104 is rotatably mounted to a corner portion of the enclosure 102 by a vertical hinge 106. The hinge 106 allows the door 104 to rotate between a closed position that prevents access to an interior portion of the enclosure 102 (as shown in
In the illustrated embodiment, the kiosk 100 further includes a coin input region, such as a hinged coin input tray 108 in which the consumer can deposit his or her coins. A display screen 112 and associated user-selection buttons (e.g., a touch screen) enables the user to make selections and provide operating instructions to the kiosk 100. The kiosk 100 can also include a voucher outlet 114 from which the consumer can receive a redeemable voucher for all or a portion of the value of the deposited coins. In addition, the kiosk 100 can include a card outlet 116 from which the user can receive a new prepaid card (e.g., a prepaid phone card or prepaid credit card) for all or a portion of the coin value, and/or a card reader 118 with which the user can reload or “top-up” an existing prepaid card or an account with a portion of the coin value.
The kiosk 100 described above is merely representative of one type of consumer-operated kiosk, commercial enclosure, or other enclosure that can include the access monitoring systems described herein. In other embodiments, other types of consumer-operated kiosks, enclosures, and machines can include access monitoring systems configured in accordance with the present disclosure. Such machines can include, for example, DVD rental kiosks (such as those operated by Redbox Automated Retail, LLC of Oakbrook, Ill.), food vending machines such as coffee vending machines, card dispensing machines, consumer electronics vending machines, gift card exchange machines, cash registers, etc. Moreover, in other embodiments other kiosks and machines can include more, fewer, or different functionalities than those described herein. Indeed, as those of ordinary skill in the art will appreciate, the systems and methods described herein can be used with essentially any type of commerce-related or other enclosure to ascertain and/or record when a door or other access panel is opened and how long it remains open, and thereby provide security against theft and/or other types of unwanted access.
In the illustrated embodiment, the kiosk 100 includes an access monitoring system 200 that comprises an identification device or identifier 226 mounted to an upper inboard corner of the door 104 proximate the hinge 106, and a reading device or reader 224 mounted to an adjacent portion of the enclosure 102. In other embodiments, however, the reader 224 can be mounted to the door 104 while the identifier 226 is mounted to the enclosure 102. Moreover, it still further embodiments the identifier 226 and/or the reader 224 can be mounted in other locations on the door 104 and/or the enclosure 102. In one aspect of this embodiment, the identifier 226 and the reader 224 are positioned such that they will be aligned and proximate to each other, or at least generally aligned and proximate to each other, when the door 104 is securely closed and/or locked against the enclosure 102.
In the illustrated embodiment, the identifier 226 is a wireless identifier, such as an RFID transponder or “tag.” In addition, in this embodiment the reader 224 is a wireless reader, such as an RFID reader. As described in greater detail below, in some embodiments the reader 224 can be operably connected (via, e.g., a USB port) to a kiosk computer for recording kiosk entry times, duration, and entering-person identification, and/or for communicating such information to a remote computer.
Although the illustrated embodiment includes a hinged door (i.e., the door 104), in other embodiments the access monitoring system 200 and/or one or more individual components, features and aspects thereof can be similarly implemented with other types of movable or removable access structures, including other types of doors (e.g., sliding doors), access panels (e.g., panels that can be entirely removed from the enclosure), etc. Accordingly, the systems and methods described herein are not limited to use with a particular type of door or other access structure.
As also mentioned above, in the illustrated embodiment the reader 224 is a wireless reader, such as a 125 kHz EM4100 or EM4102 RFID reader module in a printed circuit board (PCB) form factor with a USB port for reading EM4100 or EM4102 compatible tags. The reader 224 can include a radio frequency (RF) transmitter and receiver (“transceiver”) 431 for wireless communication 430 with the identifier 226. The transceiver 431 can be controlled by a micro processor and/or digital signal processor 433 mounted to a PCB 434. In the illustrated embodiment, the transceiver 431 is operably tethered or otherwise electronically connected to the circuit board 434 by a cable 432 (e.g., a USB cable that plugs into a USB port on the PCB 434). Moreover, in this embodiment the transceiver 431 is the portion of the reader 224 actually mounted to the outside of the kiosk panel 338 so that it faces the identifier 226 when the door 104 is closed (see
In the illustrated embodiment, the reader PCB 434 is operably connected to a host computer 438 (e.g., a central or main kiosk computer that controls all or a portion of the functions of the kiosk 100) via a communication link 436 (e.g., a USB cable). The communication link 436 enables the reader 224 to exchange information with and/or communicate information to the host computer 438. Such information can include, for example, what time the door 104 (
The routine 500 starts in block 502 when a reader, e.g., the reader 224 checks for the presence of an RFID tag, e.g., the identifier 226. If the reader detects the presence of the tag in decision block 504 (indicating the door is closed), then the routine proceeds to decision block 506 to determine whether a clock (e.g., the clock 444 of
Returning to decision block 504, if the tag is not present when the reader checks for it (indicating that the door is opened), then the routine proceeds to decision block 510 and determines if the clock is running. If the clock is not running, then the routine proceeds to block 512 and starts the clock. The routine also proceeds to block 514 and records the current time to reflect when the door was opened. In one aspect of this embodiment, in block 516 the routine can include the ability to disable all or a portion of the kiosk functionality when the door is opened. For example, if the access monitoring system described herein is used with a coin counting kiosk, the routine can disable the coin counting apparatus once the door is opened. This feature can prevent unscrupulous people from breaking into the machine and recycling the same portion of coins through the coin counting device to thereby obtain a redeemable voucher having a grossly inflated cash value. In other embodiments, the disabling feature of block 516 can be omitted.
After block 516, the routine proceeds to decision block 518 to determine if the preset period of time between checks for the presence of the tag has elapsed. Once the preset time interval has elapsed, the routine returns again to block 502 to again check for the presence of the tag. If the routine determines that the tag is still not present in decision block 504 (indicating that the door is still open), then the routine proceeds to decision block 510 where it accordingly determines that the clock is already running. From there the routine simply repeats the foregoing cycle and checks for the presence of the tag until such time as the routine determines that the tag is present in decision block 504 (indicating that the door has now been closed).
Once the routine determines that the tag is present in decision block 504, the routine proceeds to decision block 506 to determine if the clock is running. The clock will be running since it was turned on when the door was first opened, and therefore the routine proceeds to block 520 to stop the clock. From block 520 the routine proceeds to block 522 and records the time the clock is stopped, as this time corresponds to when the door is closed. In block 524, the routine 500 can optionally send a “timestamp” and/or other door access information to a remote computer, such as a computer located at a central operations headquarters remote from the coin counting kiosk. In some embodiments, a timestamp is a sequence of characters denoting the date and/or time at which a certain event occurred (e.g., a door was opened and/or the door was closed), and/or when the event is recorded by a computer. The timestamp can include, for example, information such as what time the door was opened, how long the door remained open, and when the door was closed. After block 522, the routine proceeds to block 526 and turns on or otherwise enables any portion of the machine functionality that was turned off in block 516. From block 526, the routine proceeds to decision block 508 and repeats as described above.
Timestamps from a particular kiosk can be used by, for example, a kiosk operator, in a number of different ways. For example, in one embodiment the timestamps can be compared to task logs of field technicians to ensure that only authorized persons had access to the kiosk during a particular period of time. Moreover, persons accessing the kiosk to remove, for example, collected coins, can also provide their entry logs for comparison to the timestamps to ensure that only approved personnel removed coins from a kiosk.
Each of the steps depicted in
Those of ordinary skill in the art will appreciate that the routine 500 and other functions and methods described herein can be performed by the computer 438, the reader 224, or both. The functions can be implemented by an application specific integrated circuit (ASIC), a digital signal processing (DSP) integrated circuit, through conventional programmed logic arrays or circuit elements. While many of the embodiments are shown and described as being implemented in hardware (e.g., one or more integrated circuits designed specifically for a task), such embodiments could equally be implemented in software and be performed by one or more processors (e.g., the processor 433 and/or the processor 446 of
Aspects of the access monitoring and security technology disclosed herein can be implemented in a number of useful embodiments. Such embodiments can include, for example:
This embodiment is described in detail above. When the door is opened the reader (e.g., the reader 224) no longer senses the tag (e.g., the identifier 226) and the system logs a “door open” time (via, e.g., the kiosk computer 438). When the door is closed the reader senses the tag and the system logs a “door closed” time. The door open and closed times can form a “timestamp” or timestamps for a particular kiosk. The timestamps can be uploaded daily to a remote headquarters computer along with other reporting information, or they can be electronically retrieved remotely from headquarters as needed. In the case of suspected kiosk tampering, additional steps can be taken such as placing a hidden camera (e.g., a video camera) in the kiosk and starting it to record images when the door is opened. Alternatively, a video camera can be running the entire time the machine is operating, and the timestamps can be correlated to the video to determine who had access to the machine during a particular time.
In addition to providing security, in another embodiment an RFID tag may be mounted to the kiosk enclosure in such a way as to allow a person using a hand held device, such as a handheld RFID reader to sense the tag even if the kiosk is packaged for transit. The tag could therefore be used for inventory identification early in the kiosk build and assembly process and for tracking purposes thereafter.
In this embodiment, an RFID reader or other reading device (e.g., a barcode scanner) could be mounted to a particular kiosk during assembly and used to read and record a unique ID number associated with each of the components (or at least the major components) used in the assembly of the kiosk. For example, during production assembly a tethered antenna could be plugged into the reader via a remote port and used to scan the RFID tags or other identifiers from the various internal components of the kiosk, such as a system computer, a coin counter, a coin cleaner, an LCD monitor, etc. Moreover, field technicians could be provided with an on-screen utility for removing and adding components to the kiosk. For example, a new component could be held up to the reader antenna and the unique RFID tag on the component read, and then the new component can be used to replace a malfunctioning or defunct component that is subtracted from the list of installed components. Similar to kiosk access information, this information could be uploaded to a remote system for inventory management, investigation and/or configuration control. Alternatively, the kiosk can be polled remotely from operation headquarters to obtain information about kiosk components on an as-needed basis.
In some of the foregoing examples, a door of a kiosk can be manually opened with a key or similar device, and a reader (e.g., an RFID reader) and an identifier (e.g., an RFID tag) can be used to log when and for how long the door was open. In other embodiments, however, the door can be latched shut with, for example, a solenoid driven lock that is electronically operated by detecting the presence of a particular identifier device. For example, in one embodiment personnel authorized to access the kiosk can be issued a unique “RFID key fob” (or other RFID tag or transponder device) that can be placed in a specified location on or near the kiosk to be read by a suitable reader mounted to the kiosk (e.g., an RFID reader). When the RFID key fob or similar device is suitably read by the reader, the reader transmits a signal to, e.g., the kiosk computer which activates the door opening solenoid to allow full, or at least limited access to the kiosk depending on the scope of access provided by the particular key fob code. One advantage of this approach is that if for any reason the key fob becomes lost or falls into the wrong hands, the unique code of the key fob could be remotely removed from active status via, e.g., a remote central operations computer, whereupon a new key fob would be issued to authorized personnel. This way, the lost key fob could not be used to open the door. In another aspect of this embodiment, the physical key could still be used to open the door, but the physical key would only be provided to an authorized field technician, whereas others would require the special key fob to open a particular kiosk. Although the foregoing example is described in the context of a key fob that contains a wireless identifier such as, for example, a RFID chip, in other embodiments an identifier such as an RFID chip can be included on a wallet sized card such as a credit card sized device, or on a bracelet worn on the user's wrist.
There are a number of advantages associated with various embodiments of the methods and systems described herein. One advantage, for example, is that a wireless kiosk access monitoring system as described herein can be relatively easily retrofitted to existing kiosks in the field. Moreover, the components of the system (e.g., an RFID tag or chip and an RFID reader) are relatively inexpensive components. In addition, in some embodiments these types of wireless identification systems can provide more security than a physical key, which can be easily copied. A further advantage of some embodiments is that a wireless access monitoring system can be remotely enabled and/or disabled via a communications link (e.g., the Internet) with a remote computer. Embodiments can also provide benefits such as remote access control, fraud prevention, access accountability, and configuration control as described in detail above.
The above description of various examples and embodiments of the invention is not intended to be exhaustive or to limit the invention to the precise form disclosed above. While specific examples for the invention are described above for illustrative purposes, various equivalent modifications are possible within the scope of the invention, as those skilled in the relevant art will recognize. For example, although some embodiments have been described above in the context of consumer-operated kiosks, such as coin counting kiosks, in other embodiments the methods and systems disclosed herein can be used to monitor access and/or provide security for other commercially-related enclosures, such as prepaid card kiosks, DVD rental kiosks, vending machines, cash register drawers, etc. Moreover, although some embodiments have been described above in the context of RFID tags and RFID readers, in other embodiments other types of wireless technology can be used to monitor access door status. For example, in other embodiments a machine-readable code, such as a barcode, can be affixed to one of the door or the kiosk, and a scanner, such as a suitable infrared barcode scanner, can be affixed to the other of the door or the kiosk. The barcode and scanner can be positioned such that the scanner can “read” or suitably scan the bar code when the door is fully closed.
The input devices 602 may include a keyboard and/or a pointing device such as a mouse. Other input devices are possible such as a microphone, joystick, pen, game pad, scanner, digital camera, video camera, and the like. The data storage devices 604 may include any type of computer-readable media that can store data accessible by the computer 600, such as magnetic hard and floppy disk drives, optical disk drives, magnetic cassettes, tape drives, flash memory cards, digital video disks (DVDs), Bernoulli cartridges, RAMs, ROMs, smart cards, etc. Indeed, any medium for storing or transmitting computer-readable instructions and data may be employed, including a connection port to a network such as a local area network (LAN), wide area network (WAN) or the Internet (not shown in
Aspects of the technology may be practiced in a variety of other computing environments. For example, referring to
At least one server computer 708, coupled to the Internet or World Wide Web (“Web”) 706, can perform much or all of the functions for receiving, routing and storing of electronic messages, such as web pages, audio signals and electronic images. While the Internet is shown, a private network, such as an intranet may likewise be used herein. The network may have a client-server architecture, in which a computer is dedicated to serving other client computers, or it may have other architectures such as a peer-to-peer, in which one or more computers serve simultaneously as servers and clients. A database 710 or databases, coupled to the server computer(s), stores much of the web pages and content exchanged between the user computers. The server computer(s), including the database(s), may employ security measures to inhibit malicious attacks on the system, and to preserve integrity of the messages and data stored therein (e.g., firewall systems, secure socket layers (SSL) password protection schemes, encryption, and the like).
The server computer 708 may include a server engine 712, a web page management component 714, a content management component 716 and a database management component 718. The server engine performs basic processing and operating system level tasks. The web page management component handles creation and display or routing of web pages. Users may access the server computer by means of a URL associated therewith. The content management component handles most of the functions in the embodiments described herein. The database management component includes storage and retrieval tasks with respect to the database, queries to the database, and storage of data.
Referring to
A distributed file system 754 couples the web servers to several databases (shown as databases 1, 2 . . . K). A distributed file system is a type of file system in which the file system itself manages and transparently locates pieces of information (e.g., content pages) from remote files or databases and distributed files across the network, such as a LAN. The distributed file system also manages read and write functions to the databases.
One skilled in the relevant art will appreciate that the concepts of the invention can be used in various environments other than location based or the Internet. In general, a display description may be in HTML, XML or WAP format, email format or any other format suitable for displaying information (including character/code-based formats, algorithm-based formats (e.g., vector generated), and bitmapped formats). Also, various communication channels, such as local area networks, wide area networks, or point-to-point dial-up connections, may be used instead of the Internet. The system may be conducted within a single computer environment, rather than a client/server environment. Also, the user computers may comprise any combination of hardware or software that interacts with the server computer, such as television-based systems and various other consumer products through which commercial or noncommercial transactions can be conducted. The various aspects of the invention described herein can be implemented in or for any e-mail environment.
