Contactless card product introduction
Contactless card support/protocol, command compatible with common commands , built-in hardware coprocessor, data memory for. This chip complies with the People's Bank of China's sub-passbook/electronic wallet specifications and the construction business card chip specifications. At the same time, it supports quasi (electronic wallet) and Ministry of Construction card application specifications, and has good security.
The integrated circuit in the contactless card includes main parts such as central processing unit, read-only memory, random access memory, electrically erasable programmable read-only memory and on-chip operating system. An ultra-small computer. It has the advantages of large amount of information, high anti-counterfeiting security, offline operation, and multi-functional development. The card uses a powerful and stable security controller to enhance the security of the card. Contactless cards use wireless transmission and obtain energy and data signals through radio frequency, which can meet the requirements of fast transactions (such as rapid passage of buses). The card uses a variety of chip-level anti-attack methods. It is basically unforgeable and can perform encryption and decryption operations internally. Its unique internal and external authentication mechanisms and special authentication mechanisms represented by financial card specifications can fully ensure the legality of transactions. During the authentication and transaction process, the key will not be leaked to the outside of the card. Each time it is performed through encrypted random numbers, and because of the participation of random numbers, it is ensured that the content of each transmission is different, ensuring the security of the transaction. sex. The keys used in the authentication and transaction processes are generated in a secure card issuance environment and installed in cipher text on the card and user card. The keys are not exposed during the entire process. The card's application firewall function can ensure the security independence of different applications in the same card. Financial industries with higher security requirements use cards as the standard for next-generation bank cards. The use of contactless cards can prevent counterfeit cards, counterfeit terminals, and counterfeit transactions, ultimately ensuring the security of the system.
At the same time, the large-capacity storage space of contactless cards can meet the storage of more customer information required by expected large-amount consumption applications. At this time, security is not only the security of electronic money stored in the card, but also the security of personal information. The security mechanism of contactless cards can provide good protection for this.
