Although it is more convenient to confirm the guest's identity and register information, it also increases the risk of identity disclosure, because personal information may be leaked in this way, which is unsafe. If you really need to hand in your ID card, it is recommended to confirm it with the front desk, then remind the front desk to strengthen information protection measures, and suggest that you take back your ID card when you leave the hotel.
