How to open the door with nfc

Many people think that NFC of iphone is to copy the access card and then open the door. This is normal logic, and I thought so at first. But this is not suitable for the iPhone.

The cards in the iPhone logic wallet can only be added with bank cards and Beijing-Shanghai transportation cards. This is limited, and it can't be changed without jailbreaking. There's nothing we can do.

The alternative is to add bank cards, credit cards, Shanghai traffic cards and Beijing traffic cards. Help yourself. There is no charge for the transportation card. Don't worry. (Thanks to lzp06 10 for reminding me that the bank card is highly unavailable. It is suggested to use the transportation card. )

This is the most important step. When you open your card, you will be prompted to see this next to the card reader. Let the property lady understand this as a blank card and put it on the machine to read the card. Card information will appear on their computers. Then add this information to the property management system. It's as simple as that (Yunnan FY tried it for a long time before, but it didn't work, because the card reader has a groove that the mobile phone can't touch, so you can't see the information, so everyone must pay attention)!

Remind not to tell the property to open the door as soon as you come up. They don't understand that if you talk too much, people will get bored and just find a reason to send you away. Therefore, words should be focused. Your mobile phone is a blank card, please ask him to have a look and write it into the property management system. He will understand. Don't say anything about encryption, the property system is very compatible. If you can't read the information, you've got it wrong. Be sure to look close to the card reader. These words will not work again. Please turn on service mode and try.

The principle is actually reverse thinking. IPhone does not allow copying. Let's add properties. You only add a transportation card for one purpose, so that the iphone has card information, and then add this information to the property management system.

Lock the screen, double-click the lock button to quickly open the card function. You can open the door by touching the left position of the camera.
