Can ID Cards be Replicated?

ID cards represent the special significance of personal vouchers, as well as characteristics such as storability and data encryption of second-generation ID cards, and determine that they have unique advantages and wide application prospects as access control vouchers.

There are two main modes of identity card access control: 1. Hold an ID card to authorize. 2. ID number authorization The first mode uses the ID of the IC chip inside the ID card as the card number. It is the formal ID card access control. The ID card is essentially equivalent to the traditional gate IC card, and is issued by the software system first. Authorization, after the identity card IC chip logo is written into the controller, you can use the ID card to access the card. This mode system is simple and convenient, and the basic functions are the same as those of a conventional IC access control system, and there are different people whose ID card numbers are the same, so that it is impossible to distinguish them. In addition, there is a possibility that an ordinary IC card that has the same card number can be used to copy the authorization card.

The second mode is to read the encrypted data in the ID card, usually an 18-digit ID number for access control authorization. This mode of identity card access control is not easy to copy, it relies on the second-generation ID card-specific encryption algorithm, the use of ID card internal storage of the ID number (in fact, you can also read the name and address avatar and other information), so it must use the public security The "ID card reader" authorized by the ministry can read it out. Although the security is improved, the cost is much higher than that of the first mode.

Stainless Steel Wire Rope

The endless stainless steel wire rope is made of multiple fine steel wires, which are connected end to end to form a closed loop. Mainly used to make annular Diamond Wire, widely used in the cutting of superhard materials such as silicon ingots and precious stones.
