Can the public security network find the check-in record?

Legal analysis: at least one year, the situation varies from place to place. Many places have been preserved forever. The public security system has enough information space to keep these. After the hotel is registered, the information is automatically backed up on the server of the Public Security Bureau. There are detailed records, such as when, how many people, which room, ID card scanning. The hotel scans the guest's registered ID card and uploads it to the database of the Public Security Bureau, which is convenient for the public security bureau to inquire and monitor, so even if the ID card is destroyed, the check-in record cannot be deleted. Identity card is a document used to prove the identity of the holder, which is mostly issued to citizens by governments of various countries or regions. It will be used as a tool to prove everyone's unique citizenship.

Legal basis: Article 175 of the Procedures for Handling Criminal Cases by Public Security Organs. After accepting a case, the public security organ considers that the criminal facts that need to be investigated for criminal responsibility belong to its own jurisdiction and are approved by the person in charge of the public security organ at or above the county level; If it is considered that there are no criminal facts, or the criminal facts are obviously minor and need not be investigated for criminal responsibility, or there are other circumstances in which criminal responsibility is not investigated according to law, the case shall not be filed with the approval of the person in charge of the public security organ at or above the county level.
