The invention discloses an implementation method for supporting dual protocols by utilizing an RFID chip. The method is characterized by comprising the following steps: setting one of an ISO 14443 protocol and an ISO 15693 protocol on the RFID chip as a default supported protocol on the RFID chip; electrifying the RFID chip, simultaneously receiving instructions of the two protocols, further judging the types of the received instructions, entering a communication mode of the default protocol if the instruction of the default protocol is received, and automatically switching into another communication mode when one condition is met; and not responding to the instruction and starting condition judgment when the instruction of a non-default protocol is received, judging the subsequent received instruction, switching to the communication mode of the non-default protocol if the condition is met, and responding to the instruction of the protocol. According to the implementation method disclosed by the invention, double communication protocols are realized, and the chip can preferentially enter a defaulted protocol mode during use and automatically switch to another communication protocol when the condition is met according to the service condition. Therefore, two protocol modes can be switched according to needs.
