#CMT# #/CMT# The contactless data carrier (1a) has an antenna (2) and a chip (3), the data stored on the data carrier transmitted to a data carrier reader via an antenna-based data transmission channel (15) and via an optical data transmission channel (5), in dependence on the data to be transmitted. The chip may have a data storage region which is freely accessible and a data storage region which is only accessible after an authentication procedure. #CMT# : #/CMT# An independent claim for a method for ensuring deliberate use of a contactless data carrier is also included. #CMT#USE : #/CMT# The contactless data carrier is used as a cash card used for payment for goods or services, or as a travel visa for use with a travel document. #CMT#ADVANTAGE : #/CMT# Provision of both antenna-based and optical data transmission channels prevents accidental use of contactless data carrier. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic representation of a contactless data carrier used with a reader.
