2.5.1 Hotel Guest Room Access
ZigBee-based systems can replace the magnetic key card systems used in hotels to access
guest rooms. The traditional room access plastic cards have a magnetic strip on their
back; the card reader installed on the guest door reads the information encoded into the
magnetic strip to allow or deny access to the room. Installing this reader for each door
requires wiring through the door. Alternatively, a ZigBee- based room access system
includes a portable ZigBee device that acts as the key and a battery-powered ZigBee
device inside the door that locks and unlocks it. Unlike the traditional method, the
ZigBee-based room access system does not require wiring each door, which reduces the
installation cost.
