#CMT# #/CMT# The plastic card has surface sides coated with very thin colored, intelligently controlled small displays (2), and an associated voltage supply. The associated voltage supplies are realized by printed film-back-up-batteries or solar cells (3) in the layer present under the display. The display surfaces contain certain areas which respond to contact or pressure and enable a communication, independent of other technical devices, in cooperation with the voltage supply by printed film-back-up-batteries or solar cells in the layer present under the display. #CMT#USE : #/CMT# Plastic card for use as identification card, debit card and cheque cards (Claimed). #CMT#ADVANTAGE : #/CMT# The plastic card has surface sides coated with very thin colored, intelligently controlled small displays, by which plastic cards contain an optionally changed layout, and hence save time, material and expenditure with increased security. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a plastic card. 1 : Transparent protection layer 2 : Small displays 3 : Printed film-back-up-batteries or solar cells 4 : Medium support layer. |
