Abstract: A system and method for enhancing security of an electronic transaction is described. The method comprises receiving a request for an authentication of an electronic portable transaction device in connection with a new electronic transaction involving the electronic portable transaction device; retrieving a first record of one or more previous electronic transactions involving the electronic portable transaction device from a first storage device; retrieving a second record of one or more previous electronic transactions involving the electronic portable device from a second storage device; and determining whether the first record and the second record are reconcilable.

Abstract: A system and method for facilitating wireless transactions using a smart card, the system comprising a housing having an opening configured to accept a smart card; a smart card interface configured to be coupled to the smart card when the smart card is accepted into the opening and configured to provide a data communication link with one or more processers in the smart card; a wireless transceiver configured to engage in wireless data communication with a transaction terminal when the smart card interface is coupled to the smart card; and a power source configured to supply power to the wireless transceiver and the smart card interface.

Abstract: A method and system of selectively initiation biometric security based on thresholds is described. The method includes determining a transaction amount of a current transaction involving an electronic portable transaction device, retrieving a threshold amount from a data storage device, comparing the transaction amount and threshold amount, and, if the transaction amount matches or exceeds the threshold amount, initiating a biometric authentication process.

Abstract: A method and system of selectively initiating biometric security based on thresholds is described. The method includes retrieving an access security level associated with an access domain and an access permission level associated with an electronic portable transaction device, comparing the access security level and access permission level, and, if the access security level exceeds the access permission level, initiating a biometric authentication process.

Abstract: A system and method for facilitating wireless transactions using a smart card, the system comprising a smart card configured to be coupled to a smart card carrier, the smart card comprising: one or more processors; a biometric sensor configured to capture a biometric image of a user requesting a new transaction involving the smart card; a memory for storing biometric data of an authorized user of the smart card; and a carrier interface configured to be coupled to a card interface of a smart card carrier, the smart card carrier comprising a housing having an opening configured to accept the smart card and a wireless transceiver configured to engage in a wireless communication with a wireless transaction terminal when the smart card is coupled to the smart card carrier.
