A technique for improving the security of a portable consumer device may include storing a first account identifier and a second account identifier associated with the first account identifier, the second account identifier and the first account identifier being associated with the same account on the portable consumer device. When the portable consumer device is interacting with a reader device to conduct a transaction, the portable consumer device may determine whether the transaction is a proximity transaction by sensing whether a wireless interrogation signal is being transmitted from the reader device, and determine which of the first account identifier and the second account identifier to provide to the reader device based on whether the transaction is a proximity transaction.

A technique for improving the security of a communication device may include storing a first account identifier and a second account identifier associated with the first account identifier, the second account identifier and the first account identifier being associated with the same account on the communication device. When the communication device is interacting with a reader device to conduct a transaction, the communication device may determine whether the transaction is a proximity transaction by sensing whether a wireless interrogation signal is being transmitted from the reader device, and determine which of the first account identifier and the second account identifier to provide to the reader device based on whether the transaction is a proximity transaction.

System and method for secured account numbers in proximity devices

A method and system for using a secured account number for processing proximity types of wireless financial transactions associated with portable consumer proximity devices is disclosed. In one embodiment, the method includes receiving a proximity type of wireless financial transaction request along with a secured account number from a portable proximity consumer device such as a contactless smart card, converting the secured account number to the user's real account number, and transmitting the financial transaction request along with the user's real account number to the issuer of the user's real account number for authorization and processing.

A system for managing electronic receipts is provided. According to one aspect, the system includes a portable device, a base device, a user device and an electronic receipts administration system. The electronic receipts administration system provides the base device with the appropriate data to allow the base device to generate, store and manage electronic receipts accordingly. A user uses the portable device to conduct a transaction with the base device. The base device uses a variety of information to generate an electronic receipt for the transaction. Such information includes, for example, information stored on the portable device, information stored locally on the base device and information stored on another device such as an electronic cash register. The electronic receipt is then stored on the portable device. The user device allows the user to subsequently retrieve the electronic receipt for management purposes.

Method and administration system for management of electronic receipts

A method for providing messaging between a portable device and base device is provided. The method included communicating one or more message codes maintained in the portable device to the base device. The base device then composes a message for a user of the portable device using a dictionary of message codes. The message codes have corresponding message values, which are used to generate the message for the one or more message codes. The generated message is then provided to the user.

A system for providing distributed control to process transactions is disclosed. The system includes a service provider system having associated therewith a number of rules and a number of meta-rules, a point of service device having associated therewith a number of rules and a number of meta-rules, and a portable device having associated therewith a number of rules and a number of meta-rules. The portable device uses its associated rules to determine an outcome for a transaction. If the portable device is unable to determine the outcome for the transaction, the portable device uses its associated meta-rules to either determine whether one or more of its associated rules can be altered locally in order to determine the outcome or request the point of service device to help determine the outcome using the rules and meta-rules associated with the point of service device. If the point of service device is unable to determine the outcome using its associated rules, the point of service device uses its associated meta-rules to either determine whether one or more of its associated rules can be altered locally in order to determine the outcome or request the service provider system to help determine the outcome using the rules and meta-rules associated with the service provider system.
