Do I have to deduct money if I don't return my card in Ledong Polaroid Hotel mm for one day?

The hotel doesn't check out the card, but the hotel can deduct your deposit directly.

When you check in at the hotel, the front desk will give the guest a room card. Some hotels do not charge housing deposit, but only give guests room cards, which is convenient for guests to get on and off the elevator and enter the hotel room. Guests must return their room cards when they check out. If you don't return it, you will be charged.
