In a private factory, if the recruiter asks for your ID card, will they do anything evil?

Probably not. Even if the ID card is used fraudulently, I will not be held responsible.

The Ministry of Public Security’s comprehensive reply to issues related to the replacement of lost resident identity cards pointed out: The resident identity card is a legal identity document for citizens, and its main function is to prove the identity of citizens when engaging in relevant activities. When citizens use resident ID cards to prove their identity, the relevant document-using departments have the obligation to check the consistency of the person and the certificate. Only after confirmation is correct can the relevant business be handled for the holder. If a resident ID card is lost and used fraudulently by others, the impersonator and relevant departments shall bear corresponding legal responsibilities. The person who lost the ID card does not need to be held responsible for actions he or she did not commit. The "Resident Identity Card Law" also clearly stipulates that anyone who fraudulently uses another person's resident identity card will be fined not less than 200 yuan but not more than 1,000 yuan by the public security organs, or detained for not more than ten days. If there is any illegal income, the illegal income will be confiscated.
