Zusammenfassung:	Aspects of the disclosure relate to a method for electronic funds transfer including generating a dynamic card verification value using power from a point-of-sale terminal. Aspects of the disclosure also relate to an apparatus, such as a card device, capable of displaying a dynamic card verification value or other card information using an electronic ink display integral to the card device. The card device might not have an integral battery or power source, and thus might only update the card information and refresh the electronic ink display while connected to a point-of-sale terminal or automated teller machine. The electronic ink display may persist in displaying a most recent image (e.g., a most recent dynamic card verification value) while the card device is not connected to power, and update the next time the card device receives power by being connected to a point-of-sale terminal or automated teller machine.
