Abstract: One variation of a method for controlling a reprogrammable payment card includes: at the payment card, establishing a wireless connection with a mobile computing device; receiving, over the wireless connection, a first magnetic sequence command corresponding to a first payment method, a first digital transaction credential corresponding to the first payment method, and a second magnetic sequence command corresponding to a second payment method; initiating a first mode; in the first mode, arming a controller within the payment card to drive a magnetic stripe emulator within the payment card according to the first magnetic sequence command; in the first mode, activating an integrated circuit within the payment card to broadcast the first digital transaction credential; and in the first mode, disabling operation of the magnetic stripe emulator and the integrated circuit in response to failure of a wireless connection with the mobile computing device.

Abstract: One variation of a payment card includes: a sheet comprising first and second icons; a transducer configured to output a voltage in response to an impulse on the sheet; a wireless communication module; a first input region adjacent the first icon; a second input region adjacent the second icon; a magnetic stripe emulator; and a processor configured to transition from a passive state to an active state in response a voltage output from the transducer, to receive a first magnetic sequence command associated with a first payment method and a second magnetic sequence command associated with a second payment method, to assign the first payment method to the first input region and the second payment method to the second input region, to receive a selection for the second payment method from the second input region, and to control the magnetic stripe emulator according to the second magnetic sequence command.

Abstract: One variation of a method for facilitating payment with a payment card includes: in response to an input on the surface of the payment card exceeding a first input threshold magnitude, transitioning from the off state into a primary payment mode; in the primary payment mode, activating a first timer of a first duration; in response to expiration of the first timer prior to a magnetic read head proximal the payment card, transitioning from the primary payment mode into a sleep state; in response to an input on the surface of the payment card exceeding a second input threshold in the sleep state, transitioning into a secondary payment mode; in the secondary payment mode, activating a second timer of a second duration less than the first duration; and driving a magnetic stripe emulator within the payment card according to a magnetic sequence command corresponding to a magnetic stripe card.
