How to add a hotel room card to iphone?

Apple mobile phone can't be used as a room card, and it can't be unlocked without a card reader. I know that only Huawei mobile phones can be copied now, and the information in the card can be used as a room card to open the door. Apple phones don't have this function.

The correlation is as follows

Mobile phones have replaced access cards with nfc analog access cards. Iphone6 plus has its own nfc hardware, but due to the closed nature of Apple's system, it is impossible to actively use nfc to simulate the access control card, so there is no way to replace the access control with Apple's mobile phone in routine operation. Some changes can be made to the Apple system by jailbreaking through the mobile phone. There is such a modification on the forum, but the technology is not mature and the risk of jailbreaking is high, so it is not recommended.
