While other travel companies have introduced wearable tech for payments, Meliá’s effort stands out for also being able to work at nearby participating merchants, such as a Starbucks coffee shop, a Mango fashion store, and a shop at the Katmandu theme park. Guests can walk up to the door of their guest room and use the bracelet to unlock it automatically. They can also pay for spa treatments, restaurant meals, and rides at the Meliá-owned Wave House theme park in Magaluf. Purchases are charged to the room. The bracelet syncs wirelessly by Bluetooth antennas to the hotel chain’s mobile app. Parents can use the Meliá app on their phone to control the settings for each bracelet used by a family member, such as setting a maximum spending limit for a child.
