Forget about losing your key card at the Four Seasons Resort Lanai at Manele Bay. The popular Hawaii hotel has introduced wristband entry for guestrooms.
The wristbands use radio-frequency identification to collect data. They’re also waterproof, so guests can wear them while they swim, snorkel and dig in the sand. In 2015, guests will also be able to charge food and beverage purchases to the wristbands.
