Wearable devices such as Princess Cruise’s Ocean Medallions, Royal Caribbean’s WOW Bands, or Viking Cruise’s intelligent TraceSafe devices, that come equipped with RFID technology, can act as a room key, enabling passengers to automatically open up doors and pay for drinks, services, games and other amenities. Wearable devices enable mobile identification, which also allows passengers to easily embark and disembark the ship. With just a scan of the wristband, crew members can access a passenger’s necessary information, to maintain faster boarding processes while also keeping travelers and crew members safe and accounted for.
