With the rapid development of economic globalization, RFID technology has gradually entered all walks of life, making great contributions to improving operational efficiency and corporate digital transformation. RFID ISO card and RFID reader are used more and more widely. However, in this process, RFID security issues have been exposed continuously, including RFID forgery, sniffing, tracking, denial of service, and so on.

In the face of security challenges, there are two major breakthrough directions. One is to strengthen the security and privacy of various RFID protocols and use them in conjunction with a centralized database. There is also the combination of blockchain technology and the use of blockchain technology to solve the loopholes in the traditional supply chain.

Among the various RFID security protocols, some of the security cannot meet the requirements, and some are of high complexity and cannot meet the application requirements in the Internet of Things environment. In addition, the RFID system based on a centralized database has problems such as easy data loss, tampering, and single point of failure. Therefore, many people think that combining the above two methods is the future direction of development.

The original purpose of blockchain technology is to solve economic problems. It enables users to conduct transactions without the involvement of a third party. The blockchain uses a distributed decentralized ledger as the basic structure, and data can only be added, not deleted. Therefore, compared with centralized databases, blockchain completely avoids the occurrence of single points of failure.

However, when we return to specific application scenarios, we have to face more complex considerations. Because a key factor in RFID application is cost, which makes RFID subject to some restrictions on encryption security, because the degree of encryption often has a direct impact on cost.
