US Patent 9064247 User-configurable activation of card applets

Card applets associated with an electronic wallet are activated and deactivated based on user-defined rules. Based on the rules and a device state, a card emulation state and card applet states are modified to enable or disable completion of transactions. The transactions are between a computing device and a reader such as a point-of-sale terminal. In some embodiments, a user designates a plurality of the card applets as fast cards capable of completing a transaction via near-field communication (NFC) interaction without user input at a time of the transaction.
