A Les Vegas casino is installing RFID technology to monitor how much alcohol is poured from bottles by bar staff (thanks, Manish!):
The Beverage Tracker consists of RFID-enabled liquor spouts, an RFID interrogator (reader) and software. The spouts contain a battery-powered 418 MHz RFID tag and a measuring device. Whenever a bartender pours a drink, the tipping of the bottle turns on both the tag and the measuring device, allowing the spout to measure the volume of liquor poured (in ounces) before the employee tips the bottle back up. The tag then transmits that information to the interrogator's antenna, attached to the ceiling above the bar.
What, no barman RFID tag to track who pours what?!
