  • Patent number: 8256666
    Abstract: Each portable payment device associated with a single account within a payment processing system is distinguished using track data. The track data from the portable payment device is read at each of a plurality of merchant point of sale terminals (POS). Rather than relying on the PAN alone, a merchant may utilizes the track data, or a proxy thereof, as the unique identifier for the portable payment device. The merchant may then process transactions involving the portable payment device based on the unique identifier. For example, in the transit environment the transit fare for each rider with different portable payment devices but the same account can be calculated using the unique identifier, such as the full track data read from both tracks of the corresponding portable payment devices.

  • Publication number: 20120158467
    Abstract: A system and method for facilitating the payment and collection of transit system fares using a mobile device utilizes a smart sign including near field communication (NFC) devices that communicate with a contactless element embedded within a mobile wireless device. Each NFC device is associated with a different transit location. The NFC devices may be included on the same smart sign located at one transit location or on different smart signs located at different transit locations. Alternatively, one NFC device may be included on a smart sign at a departure location and another NFC device may be activated when or after the user enters the transit system to provide proof of fare purchase. The mobile device is positioned proximate the NFC devices to activate the NFC devices and access fare and/or schedule information or purchase a fare.

  • Patent number: 8145191
    Abstract: An apparatus and method is provided to prevent contactless portable electronic consumer devices such as an RF identification device (RFID), tokens, mini-cards, key fobs, cellular phones, smart card, etc. from being wirelessly interrogated. In one embodiment, a decoy circuit capable of detecting wireless interrogation signals transmitted to a contactless portable consumer device is used to prevent one or more interrogation devices from interrogating an authentic circuit in the contactless portable consumer device.

  • Publication number: 20110016054
    Abstract: At each of a plurality of transit readers of a transit system, for each of a plurality of riders, where each rider seeks to conduct an access transaction with the transit system for access into the transit facility by using a payment device issued by an issuer in a payment system, data is read from the payment device. The data includes an encryption code that uniquely corresponds to the payment device and was created by the issuer using one or more encryption keys and a predetermined algorithm. A check will be performed, remotely and/or locally, of one or more lists of other encryption codes to determine if the encryption code is on the list. On the basis of whether the encryption code is on the list, the rider is permitted access to the facility of the transit system. The payment device need not be changed for the rider's fare. Decryption of the encryption code read from the payment device is not required to complete the access transaction.

  • Publication number: 20090239512
    Abstract: An apparatus such as a mobile phone includes a contactless smart card or payment device, where the smart card is intended for use in both commerce transaction payment and transit fare payment (or other venue access) environments. The payment device may function as both an electronic wallet for commerce transactions and as a transit system card, for access to and fare payment of transit services. Implementation of both functions may be achieved by use of a dynamic memory management system that permits data for both the payment and transit applications to be stored on the card, with the transit data and storage locations isolated from those used to store data intended for use in paying for commerce transactions. The transit application specific data may include access control data (keys, passwords, identification data) or data required for fare calculations (rates, historical data on system use), for example.

  • Patent number: 7567920
    Abstract: A method for allowing on-line authorization in an access environment. The method includes receiving a request for access to a location at a gate access device from a user. After receiving the request for access to the location, an authorization request message is generated. The authorization request message includes an authorization to charge a predetermined amount of money. The authorization request message is then sent to an issuer for approval. An authorization response message is then received. The authorization response message indicates whether or not the charge is authorized or not authorized. If the authorization response message indicates that the authorization response message is authorized, then the user is allowed to access the location.

  • Publication number: 20080208681
    Abstract: A mobile device is provided with payment data to enable the mobile device to complete a purchase transaction at a collection terminal. The mobile device requests and receives a payment data value over a wireless network to configure the mobile device as an electronic wallet such that a subsequent purchase transaction may be completed using the payment data value stored on the mobile device. A transit fare may be paid using the mobile device in communication with a back end server that collects transit information and calculates the transit fare. The mobile device may also access payment data, transit fare products and account information from the back end server via a wireless network.

  • Publication number: 20080179394
    Abstract: At each of a plurality of point of sale terminals (POS) of a transit system, for each of a plurality of riders, where each rider seeks access into a facility of the transit facility by using a payment device issued by an issuer in a payment system, data is read from the payment device. The data can include an identifier for an account issued by an issuer. For each such access, a communication including the account is addressed to a network address of a system remote from the payment processing system and remote from each of POS terminals. A response to the communication is received that includes information as to the validation of the access based upon the account being on a list keep by remote system. When the received information contains the validation of the access, the rider is permitted access to the facility of the transit system and the payment device is unchanged for the fare of the access to the facility of the transit system.
