Starwood Hotels announced last year its intentions to allow members of its SPG rewards program to unlock doors using their smartphones. Now it’s taking things one step further and, as of Friday, the official launch day of the Apple Watch, SPG members can unlock hotel room doors with their Apple Watch.

That’s pretty darn cool.

The new application allows guests to check-in, view information on the hotel and stay dates, check the status of their rewards account and more. That means guests can arrive at the hotel, skip the front desk entirely, walk up to their room, tap the door, and settle in.

“After registering for SPG Keyless, the Apple Watch will automatically send guests their room number and will function as their hotel room key at any SPG Keyless enabled Starwood hotel allowing guests to bypass the front desk (where available),” the company said Friday.

The special door locks work using Bluetooth technology and were created with ASSA BLOY, Starwood said. It’s not supported in every hotel just yet, but there are plenty that already offer the service, including 100 Aloft, Element and W hotels, with plans to embed the option in more than 30,000 hotel rooms soon.

The real value of the Apple Watch, and smartwatches in general, is still up for debate. But if you’re a fan of the future, this certainly helps you feel like you’re living in it.
