Alternatively, the radio frequency data may be modulated by a modem built in the read-write processing chip and then written into the chip.
Further, the method comprises the following steps S21-S22:
s21, if the decrypted data are judged to be illegal, skipping to execute the step of decrypting the request data to obtain decrypted data, and accumulating the decryption times;
s22, when the decryption times reach a second preset times, the wireless communication connection with the chip is disconnected.
