How to connect the access control system with the property information system?

Connection method between access control system and property information system;

1. It is impossible to copy and read the access card by using the NFC function of the mobile phone.

2. First of all, it is necessary to find out what the access card of the community is. Common access cards are ID card and IC card. The full name of ID card is identification card, which is an unwritten induction card with a fixed number. IC cards are classified as encrypted, semi-encrypted and unencrypted. NFC can only copy IC cards, and it is not encrypted. This kind of access card is very convenient for direct simulation, but now the access cards in the community are basically encrypted IC cards.

3. Of course, mobile phone manufacturers have also improved the encrypted access card. Some models support the creation of blank cards on mobile phones. Users can go to the residential property, let the property write the encrypted card information into this blank card, and let the mobile phone simulate the encrypted IC card. But whether the property agrees to give it to you is another matter. After all, the access card is closely related to the safety of the community, and the property generally does not write the information of the access card on the mobile phone.

4. Access cards, which require very high security performance, must not be copied by mobile phones, which will make it lose its meaning of existence, and now regular access cards do not support analog copying, but I suggest you be more careful. It is said that there are access card replicators on the market now, and everyone can buy them. There is no legal restriction. If you are used by criminals, you can imagine how serious the consequences are. Don't leave your access card and room card easily.
