Product Features:
The Hotel Key Card Switch is self-powered and the simple act of inserting or removing the card generates enough energy to send a wireless signal to wireless receivers within the room. To operate the switch, guests simply insert their key card in the slot when they enter the room and then remove it when they leave.
