Enter the factory with someone else's ID card and ask for fingerprints. Can I still punch in?

First of all, it is illegal to enter the factory with someone else's ID card. Secondly, even if no one investigates your illegal behavior, you can only use your factory ID card for future social security and medical insurance, which is troublesome. You may not enjoy social security and medical insurance in the future.
