The difference between IC card and UID card \/CUID card is that its internal chip structure is different.
IC card adopts non-contact radio frequency identification technology, its internal chip includes CPU, memory and interface, etc., mainly used in finance, transportation, access control and other fields; The UID card \/CUID card uses contact or non-contact radio frequency identification technology, and its internal chip mainly includes UID number and some simple logic circuits, which are mainly used in intelligent logistics, anti-counterfeiting traceability, commodity management and other fields.
Therefore, the application scenarios and functions of IC cards and UID cards \/CUID cards are different. It is worth mentioning that the CUID card is an upgraded version of the UID card, and its internal chip adds a complex encryption and decryption circuit, which can improve the security of the card.
