What should I do if I don't bring my ID card when staying in a hotel? There are photos in the mobile phone.

In this case, you can use the photo of your ID card, other valid documents, identity documents issued by the public security bureau or police station, and electronic identification.

1. You can try to use the ID photo in your mobile phone as a valid certificate. In some areas, as long as the photo of the ID card in the mobile phone is shown and confirmed, it can be used as a valid identification.

2. Try to use other valid documents, such as passport, driver's license or residence permit. These documents can also serve as proof of my identity.

3. If you don't have any valid documents, you can try to issue identification documents to the public security bureau or police station near the hotel. Generally speaking, you can stay in a hotel with a permit.

4. If you have registered your electronic ID, you can try to use it to stay in the hotel. Click "electronic identity" in the ID list of Alipay platform, fill in relevant information for face recognition, and then apply for electronic identity to stay in the hotel.
