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.

A method is disclosed. The method includes interacting with a gate access device that is capable of preventing access to a location, where the gate access device subsequently sends an authorization request message to an issuer for approval, the authorization request message including a request to charge a predetermined amount of money to pay for access to a location, and entering the location if the gate access device receives an authorization response message indicating that the charge is authorized.

Systems and methods of converting transactions to a new currency and tax processing based on the location of the mobile communication device. The systems and methods send transaction information including a transaction amount associated with a transaction conducted between a merchant and a consumer at an access device, to a server computer. The server computer determines a location of a mobile communication device operated by the consumer and converts an transaction amount to a currency based on a conversion rate based on the location of the mobile communication device or determines a tax amount based on the transaction amount and based on the location of the mobile communication device. The method also receives the converted transaction amount or the tax amount.
摘要:
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.
摘要:
A portable consumer device using a secondary PAN is disclosed. The portable consumer device includes a secondary PAN associated with a primary PAN, where the secondary PAN has at least one end portion that is the same as the primary PAN, but has a middle portion of that is different than the primary PAN.
摘要:
An apparatus and method is provided to shield contactless portable electronic consumer devices such as radio frequency identification devices (RFID), tokens, mini-cards, key fobs, cellular phones, smartcards, etc. from wireless interrogation. In one embodiment, a contactless portable consumer device which includes a first antenna is shielded from unauthorized wireless interrogation with a radio frequency (RF) shield. The RF shield includes electrically conductive, non-ferromagnetic material and is configured to prevent unauthorized data transfer between a second antenna external to the portable consumer device and the first antenna.
摘要:
A method for conducting a secure transaction using a secondary PAN is disclosed. The method includes providing a secondary PAN associated with a primary PAN, where the secondary PAN has at least one end portion that is the same as the primary PAN, but has a middle portion that is different than the primary PAN.
摘要:
A portable consumer device is disclosed. An electromagnetic shield is provided in the portable consumer device that is capable of preventing communication between the portable consumer device and an interrogation device. The shield is movable between a distal position in which communication with the interrogation device is enabled and a proximate position in which the shield prevents the transmitting antenna from communicating with the interrogation device.
摘要:
Processing an access transaction involves receiving application data from a portable consumer device at an agency reader for use in connection with a transaction, the application data having a predetermined data field configuration for processing the transaction by an issuer of the portable consumer device, and accessing at least one data file of the portable consumer device at the agency reader, wherein the configuration of the data file is determined by the issuer and stores agency data associated with use of the portable consumer device for the transaction.
