CPU Card

‌CPU card‌, also known as smart card, is an integrated circuit card that contains a microprocessor (CPU), storage unit (including random access memory RAM, program memory ROM, user data memory EEPROM) and chip operating system (COS). A CPU card equipped with COS is equivalent to a microcomputer, which not only has data storage function, but also has command processing and data security protection functions.CPU cards include contactless CPU cards, contact CPU cards and dual-interface CPU cards. CPU series cards are widely used in public transportation, security, campus, consumption, water meters, electricity meters, identity recognition and other industries with high security requirements.
