CONTACTLESS RADIO FREQUENCY MAGNETIC FIELD DATA TRANSMISSION CARD AND ITS APPLICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a contactless radio frequency magnetic field data transmission card and its application system.

SOLUTION: A magnetic field identification chip, a micro processing unit and an antenna module are combined to construct the contactless radio frequency magnetic field data transmission card, so that messages can be communicated with a radio frequency magnetic field identification reader according to a transmission protocol. Applications can be very wide for use in an e-card or an e-purse or the like.
