With the app, users can use their phones to perform check-ins/outs, call for hotel services such as room service, laundry, hotel facility booking, and even turn their phones into an in-room phone extension. The app will let the phone function as a key, control the TV, lighting, AC and other in-room functions provided at the hotel. However, it will only be limited to VIPs at the hotel (initially – if all goes well, you can expect it to be expanded) so not everybody will have access to such convenience. Hopefully this app/service will catch on in the future, and eventually replace the need for keys in hotels. What do you think?
