RADIO FREQUENCY (RF) APPARATUS, RF CARD READER, RELATIVE COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

A Radio Frequency (RF) apparatus, RF card reader, relative communication system and communication method are disclosed. The RF apparatus (100) comprises a first RF transceiver module (101), a first RF antenna (102), a magnetic induction and receiving module (104). The RF card reader (200) comprises a second RF transceiver module (201), a second RF antenna (202) and a magnetic emission module (204). There are two communication channels with two different characteristics between the RF apparatus and the RF card reader for controlling distance through magnetic fields, authenticating identities through the magnetic fields and radio frequencies, and communicating information through the radio frequencies.
