1. A smart card carrier comprising: a housing having an opening configured to accept a smart card, the smart card comprising a biometric sensor for capturing a biometric image and a memory for storing a biometric reference template of an authorized user;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 processors 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; anda power source configured to supply power to the wireless transceiver and the smart card interface. 2. The smart card carrier of claim 1, wherein the wireless transceiver is configured to communicate over one or more of Bluetooth, Wi-Fi, near field communication, and RFID. 3. The smart card carrier of claim 1, further comprising a user interface, wherein the user interface comprises one or more indicator lights and wherein the indicator lights are configured to communicate a status of the transaction to the user. 4. The smart card carrier of claim 1, further comprising a user interface, wherein the user interface comprises a text display and wherein the text display is configured to communicate a status of the transaction to the user. 5. The smart card carrier of claim 1, wherein the smart card interface is further configured to supply power from the power source to the smart card when the smart card interface is coupled to the smart card. 6. The smart card carrier of claim 1, wherein the user interface comprises a number pad and wherein the number pad is configured to allow a user to enter a security pin associated with the smart card. 7. The smart card carrier of claim 1, wherein the housing comprises a top face and a bottom face that are parallel to each other and separated by a smart card space, wherein the smart card space is enclosed on three sides. 8. The smart card carrier of claim 7, wherein the smart card comprises a biometric sensor, and the top face or bottom face are designed to allow access to the biometric sensor. 9. The smart card carrier of claim 8, wherein the length of the top face or the bottom face is shorter than the length of the other of the top face or bottom face to allow access to the biometric sensor. 10. The smart card carrier of claim 8, wherein the top face or bottom face includes an aperture configured to allow access to the biometric sensor of the smart card. 11. The smart card carrier of claim 8, wherein the biometric sensor is a fingerprint sensor. 12. The smart card carrier of claim 1, further comprising a processor, wherein the processor of the smart card carrier is configured to engage in data communication with the wireless transceiver and further with the one or more processors on the smart card. 13. The smart card carrier of claim 12, wherein the one or more processors on the smart card comprise a biometric controller configured to generate a biometric image template based on the biometric image captured by the biometric sensor disposed on the smart card, and the processor of the smart card carrier is configured to perform a matching between the biometric image template received from the smart card and a biometric reference template. 14. The smart card carrier of claim 13, wherein the one or more processors in the smart card further comprise a processor configured to perform the matching between the biometric image template and the biometric reference template when the smart card is not coupled to the smart card interface of the smart card carrier. 15. The smart card carrier of claim 1, further comprising a location-determining component. 16. A method of facilitating wireless transactions with a smart card through a smart card carrier, the method comprising: receiving from a wireless transaction terminal a request related to a transaction involving the smart card;engaging in data communication related to the request with one or more processors in the smart card through a smart card interface coupled to an interface on the smart card, the smart card comprising a biometric sensor for capturing a biometric image and a memory for storing a biometric reference template of an authorized user; andtransmitting a response to the request to the transaction terminal through the wireless transceiver. 17. The method of claim 16, further comprising the step of authenticating a user of the smart card. 18. The method of claim 17, wherein the step of authenticating the user comprises: receiving a user input of a personal identification number;comparing the user input with a stored personal identification number for a match; andif a match is found, outputting a response to the request to the interface of the smart card. 19. The method of claim 17, wherein the step of authenticating the user comprises: receiving a user input of a biometric signature;comparing the user input with a stored biometric for a match; andif a match is found, outputting a response to the request to the interface of the smart card. 20. The method of claim 16, wherein the wireless transaction terminal is a mobile device. 21. The method of claim 16, wherein the wireless transaction terminal is a contactless smart card reader. 22. The method of claim 16, further comprising the step of supplying power to the smart card via the smart card interface.
