WORKING METHOD OF NFC TOKEN

摘要

A working method of an NFC token. The method comprises: a micro control unit in a token performing system initialization; resetting a near field communication chip in the token and sending a near field communication chip setting instruction to the near field communication chip; waiting to receive a near field communication chip setting instruction return value; upon receiving the near field communication chip setting instruction return value, sending a first preset instruction to the near field communication chip; waiting to receive a first preset instruction return value; and upon receiving the first preset instruction return value, sending a second preset instruction comprising a dynamic password to the near field communication chip. The present invention has the beneficial effects that: the token is well compatible with a mobile platform, and is convenient to use, thereby simplifying the operation procedure of a user.

主权项

1. A working method for an NFC token, comprising:
Step 1) performing, by a micro control unit of the token, system initializing; Step 2) resetting, by the micro control unit, a near field communication chip of the token; Step 3) sending, by the micro control unit, a setting near field communication chip instruction to the near field communication chip; Step 4) waiting, by the micro control unit, for a return value of the setting near field communication chip instruction returned from the near field communication chip; Step 5) sending, by the micro control unit, a first preset instruction to the near field communication chip when the micro control unit reads the return value of the setting near field communication chip instruction returned from the near field communication chip; Step 6) waiting, by the micro control unit, for a return value of the first preset instruction returned from the near field communication chip; Step 7) sending, by the micro control unit, a second preset instruction containing a dynamic password generated by the token when the micro control unit reads a return value of the first preset instruction returned from the near field communication chip; before sending, by the micro control unit, a second preset instruction containing a dynamic password generated by the token, the method further comprising computing and generating, by the micro control unit, the dynamic password.
