Portable E-wallet and universal card

摘要

Universal cards are used in place of all the other traditional cards which a person may want to carry. The universal card can include a short range communications transceiver to communicate with a mobile device. The mobile device can include a user interface and an e-wallet application so that the user can interface with the e-wallet application for programming the universal card via the short range communication link. Once programmed, the universal card emulates a function of a traditional card.
