There is no problem for men and women to have only one ID card.

Two people, a man and a woman, can't check in with only one ID card.

According to the relevant information, the original ID card of the hotel needs to be provided before checking in at this stage. If citizens sneak in to avoid the hotel, they will be punished if they are found by the public security department. Therefore, it is recommended that both parties provide ID cards when they check in.
