Why can't the hotel room card use nfc?

This cannot be used for the following reasons:

1, the device does not support: NFC is a near field communication technology, and hardware devices supporting NFC are required to read and write. If the hotel's door lock is not equipped with NFC technology, then the room card cannot use NFC function.

2. Safety considerations: hotel locks are all unlocked by room cards, which ensures the safety of rooms. If the NFC function is turned on in the door lock system, it may lead to other security problems.

3. Cost: It may cost a lot to upgrade the door lock equipment. If the hotel's old door lock equipment cannot support NFC, it needs to be replaced, which will increase the hotel's cost.
