Abstract
Exemplary embodiments relate to updatable displays for transaction cards, such as credit cards or event passes. The displays may be, for instance, an electrophoretic or memory liquid crystal diode display. The transaction card may include a contact pad capable of engaging in wireless communication. Information may be exchanged between the transaction card and a mobile device or terminal, where a processor on the mobile device processes the received information to generate displayable information. The processor updates the display with the displayable information. The contact pad may be electrically connected to the display, and the display may derive electrical power to perform the updating from the wireless communication. For example, where the wireless communication is a near field communication (NFC), a radio frequency field may be generated that supplies enough power to run the processor and at least partially update the display.
