How does NFc open the electric retractable door

First, we need to turn on the wallet function of the mobile phone.

Step two,

On the wallet page, there is a special card area. Click "door key" to go to the next page.

But there are bank cards, transportation cards, EID, membership cards, driver's licenses, driving licenses and passports on the page, which can be added and simulated.

Step three,

Take out our access card, point it at the back of the phone and turn on the NFC function.

Simulate the existing mobile phone door key.

Step four,

Wait a moment, the page will show that the card was read successfully, and then add the name of the access card, including home, community, company, etc.

At present, only unencrypted door keys with frequency of 13.56MHZ are supported. Some encrypted keys can be unlocked by consulting properties, and then added successfully.
