HotelTonight, a last-minute mobile-only booking app, has added keyless entry and mobile check-in features that will likely become a routine part of the travel experience within five or 10 years, CEO Sam Shank said Wednesday.

The experimental features were introduced as part of the Google I/O developers conference. HotelTonight is one of the companies capitalizing on the trend for mobile in travel, as its booking and other features are only available through an app.

"What was seen as a niche has become more mainstream," Shank said in an interview with CNBC.
