In today's hotels, hotel owners and hotel owners use card locks to control the movement of guests, crew and other staff. These hotels use devices called hotel power switches or hotel holder cards to control power consumption and prevent energy loss. This device gives the hotel owners the ability to control the power consumption of the room. These devices act like smart fuses. They will not be able to use electricity, lighting, TVs or even electrical outlets until guests or hotel staff enter their room power card. After inserting the card (depending on the type of power switch and the technology used in them), the power switch will release the power with the relay embedded in it and all the electrical equipment connected to this system will be usable. With optical or mechanical technology, this device introduces electricity to the consumer by inserting any type of card and turning off the light.
