Because the hotel's identity scanning system failed to check in, is it safe for the hotel to hold my ID card overnight?

Although the hotel's identity scanning system failed to check in, the hotel kept the ID card overnight for security reasons. This is to ensure the authenticity and legality of the ID card to prevent possible fraud.

In most countries and regions, it is illegal to possess someone else's identity document. Therefore, the hotel chose to temporarily withhold the ID card for its own risk control and compliance with legal regulations.

If you have any concerns or concerns about this, you can consult the hotel's policies and procedures or contact your local legal agency for more information. Generally speaking, how this situation is handled will vary by region and specific policies.
