Enhanced near field communication terminal, smart card and communication method thereof
First Claim
1. A smart card communication method, for communication between a smart card and an NFC contactless front-end chip, comprising:
- when installing a contactless payment application, the smart card recording a communication standard adopted by a contactless payment system corresponding to the contactless payment application, wherein the communication standard is identified by identification information provided by the contactless payment application;
further comprising;
for each card application gate, the smart card judging whether a contactless payment application corresponding to the card application gate exists based on the identification information;
if yes, creating a pipe between the card application gate and a corresponding card RF gate in the NFC contactless front-end chip.
