然而，在RFID-SIM应用中容易出现编码不够安全、编码传输过程中容易出错的问题。例如，近几年一些RFID-SIM芯片的加密方法被攻破，甚至一些加密芯片被完整复制，使得以此为基础的充值和消费交易无保障。However, in the application of RFID-SIM, it is easy to have the problem that the encoding is not safe enough and the encoding transmission process is easy to make mistakes. For example, in recent years, the encryption method of some RFID-SIM chips has been broken, and even some encryption chips have been completely copied, making the recharge and consumption transactions based on this unsecured.
