When did the hotel pull out the room card?

When the hotel room card is inserted and pulled out, it can be found through the front desk computer system.

The room card is a magnetic card used to open the door and use electricity when we check into the hotel. When we use the room card to open the door and plug in the electricity, it will be displayed in the hotel system before we leave, so that we can find it.
