METHOD FOR MAKING SMART CARDS CAPABLE OF OPERATING WITH AND WITHOUT CONTACTS

摘要

#CMT# #/CMT# The smart card fabrication commences with formation of an antenna (11) with at least two turns on the card base (10). The antenna has its turns placed outside the external card contact pads (12). An insulating bridge (13) is formed over the antenna turns to allow connection of the ends of the antenna to the contact pads. The insulating bridge is formed by deposition, and a conductive strip is then laid over the bridge. #CMT#USE : #/CMT# Mixed operating mode smart cards #CMT#ADVANTAGE : #/CMT# Reduces risk of damage to antenna while the card is being machined to accept other components. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the card 11 : Antenna 10 : Card base 12 : External card contacts 13 : Insulating bridge for antenna connections.
