The Trick With The Keycard
Hotels got rid of traditional keys for hotel rooms a while back. The reason being, they adopted keycards that save tons on electricity bills. For those familiar with how keycards work, you slip your keycard into a slot in the wall, which activates and turns on your room’s electricity. These slots are usually next to the door when you first enter your room.
Most people aren’t aware that each room’s slot doesn’t require a specific keycard, you can place literally any kind of card in there, and it’ll activate. Say you have your devices charging, the air conditioner blasting, and you want to leave your lights and everything on – simply stick a business card or gift card in there while you’re out and about.
