Can I copy the access card?

I believe everyone is familiar with the key chain card that is forbidden by the door, because we use it every day. At present, the key chain cards used for access control are generally IC chip, ID chip and cpu chip card. No matter what kind of chip it is, it can be made into different colors and shapes. Many merchants will ask, can the access key chain card be copied? The following small series will explain it to you. =

Keychain card is a kind of special-shaped card with different shapes, which is made by encapsulating the chip coil with ABS shell and filling epoxy resin through ultrasonic welding. Screen printing, code spraying and code engraving are all possible. Dust-proof, waterproof and shockproof. There are dozens of shapes to choose from, which can package various types of chips.

At present, the key chain cards used for access control are mainly inductive ID cards and inductive IC cards. The advantage of inductive ID card chip is low cost. One card per person, generally safe, can be connected to a microcomputer, and has a record of opening the door. But the disadvantage of chip card is that the card is easy to be copied; Both directions are difficult to control. Therefore, the access key chain cards or community access key chain cards in this period can be copied, and the security is very poor.

As a key chain card, the inductive IC chip card has no contact with the equipment, and it is convenient and safe to open the door. The data is at least ten years, and the security is high. It can be connected with a microcomputer, open the door for recording and two-way control. The most important thing is that cards are difficult to copy. At present, with the development of IC card technology in the market, the cost of IC card is gradually decreasing, so IC card is the mainstream in the market at this time.

Now the key chains that can be copied on the market are all ID cards, and IC cards are generally not easy to be copied. The current access key chain card can also be packaged into CPU chip card, which is more advanced than IC card, but the cost is relatively higher. Therefore, the choice of accessing the key chain card should be based on the specific situation of the business.
