Of course. According to relevant information, there are two room cards, one for electricity and the other for opening the door. Generally, there is only one room card in a regular hotel, but there are no two room cards in a room. But if you need to enter the room, but your friend has a room card and is not around, you can talk to the front desk clerk.
