Hilton Worldwide plans to equip nearly all of its hotels globally with digital check-in and room-selection capabilities by the end of this year,

the company announced this week. The technology enables Hilton HHonors members to check in via their mobile devices or computers at 6 a.m. on the day before their stays and choose their rooms from either a floor-plan map or room list. Hilton plans to have the capabilities at U.S. properties in the Waldorf Astoria, Conrad, Hilton, Hilton Garden Inn, Homewood Suites and Home2 Suites brands by the end of the summer and at more than 4,000 of its more than 4,100 properties worldwide by the end of 2014. Next year, Hilton also will begin to equip rooms with technology enabling guests to use smartphones as their room keys upon arrival, with most rooms across its portfolio equipped with the technology by the end of 2016, according to Hilton. During that same period, Hilton will expand digital check-out capabilities currently available at U.S. hotels to its properties worldwide.
