ABSTRACT:
A payment card with a display and/or dynamic magnetic stripe that operates using power received from an electro-magnetic/RF signal, without the need for incorporating a battery within the payment card. In one example, a payment card includes a receiver for receiving an external electro-magnetic signal and converting it to an electrical signal for powering the payment card; a CPU coupled with the electrical signal of the receiver; a display (i.e., a persistent display) for displaying data, wherein the display receives power based on the electrical signal from the receiver; and a dynamic magnetic stripe storing magnetically readable data, wherein the dynamic magnetic stripe receives power based on the electrical signal from the receiver. Responsive to the electro-magnetic signal received by the payment card, the data displayed on the display and stored in the dynamic magnetic stripe is changed. Methods relating to a payment card are also disclosed.
