CPU is the abbreviation of central processing unit, so by extension, CPU card is also a card with central processing unit, and indeed CPU card is equivalent to a microcomputer which can analyze, intelligently store and intelligently encrypt data. In recent years, CPU cards have been gradually transferred from the public sector to the commercial sector, such as membership cards and access control cards.

What are the main applications of CPU cards and what are the types of CPU cards?What are the main applications of CPU cards and what are the types of CPU cards?


The CPU card we are talking about here is a generic term, which can be divided into contact and contactless CPU cards in terms of reading and writing methods, in addition to the difference between different types of chips from different production companies.


Contact CPU card products: support ISO/IEC7816T=0/1 protocol, IC card specification for gas industry, IC card specification for transportation industry, IC card specification for social security industry, etc. Built-in hardware DES3DESRSA co-processor, data memory is 8K-64K EEPROM, with high security.


Contactless CPU card products: support ISO/IEC14443TYPEA/B protocol, composite national Ministry of Construction contactless CPU card COS technical requirements and PBO2.0 financial IC card specifications, etc. Built-in hardware DES3DESRSA co-processor, data memory is 8K-64K EEPROM, with high security.


Dual interface CPU card products: In addition to the protocols and specifications of contactless and contact CPU cards, they also comply with javacard2.2.1 specification and Globalplatform2.1.1 specification. Capacity support: 8K-80K. features: support Mifare emulation / pass bank card testing center security testing / direct DES3DES cryptographic algorithm / support RSAPKI algorithm up to 2048 bits.


CPU card related chips are: Fudan FM1204, FM1208, FM1216, FM12DE32; NXP (NXP) MifareDESfire2K, MifareDESfire4K, MifareDESfire8K, etc.
