Hello, IC access card UID and CUIB are terms related to access control systems, where UID refers to the unique identifier of the card, and CUIB refers to the integrated circuit board in the access controller.
The specific differences are as follows:
1. UID is the unique identifier of a card. It is a string of numbers used to identify the card, usually pre-coded by the manufacturer. CUIB is a circuit board in the access controller, which contains various circuit components such as processor, memory, input and output interfaces.
2. UID is the data on the card, which can be read by the card reader. CUIB is a circuit board in the access controller and one of the core components of the access control system, responsible for card reading, identity verification, access control and other functions.
3. The length and format of Uids can vary according to the specific card type. The design and function of CUIB depend on the needs and specifications of the access controller.
In general, UID and CUIB are both key components in access control systems, but their roles and characteristics are different. UID is mainly used for card identification and authentication, while CUIB is the core component of the access controller, responsible for controlling the switch and security of the access control.
The answer is as follows: IC access card UID refers to the unique identifier on the access card, usually a hexadecimal string, used to identify the identity of the cardholder and authorize access to the access area.
CUIB is the unique identification code on the access controller, usually a string of numbers or letters, used to identify the access controller and manage the parameters and Settings of the access controller.
The difference between them is that the IC access card UID is the unique identification code of the access card, while CUIB is the unique identification code of the access controller. Both are used to identify different devices or user identities in the access control system, but their scope and application scenarios are different.
The difference between uid and cuid is:
< br >
1, UID responds to the backdoor command, CUID does not respond to the backdoor command;
< br >
2, UID card ID can be changed and use the backdoor instruction to change the ID, CUID card ID can be changed and use the ordinary write instruction to change the ID.
The difference is as follows

UID card: A common copy card that can erase and write all sectors repeatedly. If the access control card has a firewall, it becomes invalid.

CUID: Upgrade replication card, can repeatedly erase all sectors, can penetrate most firewalls.
