Abstract
In general, embodiments of the present invention provide a card (e.g., identification, debit card, credit card, smart card, etc.) having a dynamic information display panel integrated therein. The display panel is typically activated when user uses the card. This can occur when the card is swiped, and/or is powered up via an integrated energy panel (e.g., by an external light source). Alternatively, the card can be powered by RFID coupling, smart IC contact, battery, etc. Upon powering up, displayed information is used to: identify the user; and/or show private information to user only. Along these lines, displayed information can remain in card memory and/or on the display until next transaction, or it can be deleted after a programmed duration.
