Payment card dynamically receiving power from external source
First Claim
1. A payment card comprising:
- a receiver to receive an external electro-magnetic signal, said receiver operable to convert said electro-magnetic signal to an electrical signal for powering the payment card;
a CPU coupled with the electrical signal of the receiver, the CPU operable to generate one or more data signals; and
a display to receive at least one of the one or more data signals from the CPU, wherein the display is operable to display security data and to receive power based on the electrical signal from the receiver,wherein, responsive to the electro-magnetic signal received by the payment card, the CPU changes the security data displayed on the display.

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.
