One five-star hotel has installed an RFID system to identify guests as they approach its bar. The solution can tell bartenders the name and specific preferences of an approaching patron, enabling them to provide personalized greetings and assistance. The system consists of active 433 MHz RFID tags built into key fobs carried by guests, as well as readers that awaken and receive those tags’ transmitted ID numbers, and then forward those IDs back to a gateway that communicates with a cloud-based server. A tablet computer mounted behind the bar can then display information about the customers carrying the fobs. Employees working at the reception desk explain how the key fob works to the guest. Guests who opt not to be recognized via the fob are told they can simply leave the device in their room when visiting the bar.
