Can the encrypted access control ic card be copied?

The information in IC card cannot be copied after encryption, and the password verification is wrong. The card itself has self-destruction function, so the data in the IC card is safe and reliable. The requirement for network is not high, and the security and reliability of IC card make it less real-time and sensitive in computer network application, so it can be applied in the environment with low network quality or offline/.

The reading and writing mechanism of IC card is simpler, more reliable, cheaper and easier to popularize and maintain than magnetic card.

If the user's IC card is lost or stolen, the user can report the loss or replace the card at the storage point where the card is located; The service life of IC card is subject to the validity period printed on the back of the card.

Extended data:

According to the different types of embedded chips, IC cards can be divided into three categories:

1. memory card: The integrated circuit on the card is a programmable read-only memory called EEPROM, which can be erased electronically. The memory card itself has no hardware encryption function, only encrypts files, which is easy to be cracked.

2. Logic encryption card: The integrated circuit in the card includes encryption logic circuit and programmable read-only memory EEPROM. The encryption logic circuit can protect the security of the card and the data in the card to a certain extent, but it can only play a low-level protection role and cannot prevent malicious attacks.

3. Smart card (CPU card): The integrated circuit card includes the central processing unit (CPU) of CPU, the programmable read-only memory (EEPM) of RAM and the random access memory (RAM), because the card (chip operating system) is a card with data fixed in Carol, which is divided into external reading and internal processing to ensure the security and reliability of data.
