Hilton Worldwide is to roll-out mobile room keys at several of its US hotels across four brands, which will allow guests to check-in with smartphone apps.
The new service will be available for members staying at the US properties of the Hilton Hotels & Resorts, Waldorf Astoria Hotels & Resorts, Conrad Hotels & Resorts and Canopy by Hilton brands.
The technology will be rolled-out in three phases across four brands with pilot testing planned at ten US properties in early 2015.
Mobile room key will be allowed at all US properties of Conrad Hotels & Resorts starting early 2015 and roll-out will commence in the middle of next year.
The technology will be initially available on the Apple and Android versions of the Hilton HHonors mobile app.
Members can use their smartphone to access other areas of each facility that need a room key such as the fitness centre, executive floors, elevators and parking facilities.
Hilton plans to install the technology across 11 worldwide brands in 2016.
Hilton Worldwide global head of digital Geraldine Calpin said: "Our mobile room key technology gives our guests greater choice and control over their entire experience.
"Never before has a hotel guest been able to check-in, select their room from a digital floor plan, request items to be ready upon arrival, and then access their room via their smartphone and find it exactly the way they requested it."
Hilton Worldwide’s portfolio of 12 global brands feature more than 4,250 managed, franchised, owned and leased hotels and timeshare properties, with more than 700,000 rooms in 93 countries and territories.
