Gadget Lust: Unlock Your Hotel Room with Your Smartphone

Last Updated Jun 4, 2010 12:16 AM EDT

Need to get into your hotel room? As the saying goes, there's an app for that -- at least if you're staying at a Holiday Inn.

If you hate to carry a room key (easy to lose, hard to fish out of your wallet), you might think about booking future business trip stays at a Holiday Inn, where you can access your room using your iPhone, Android, or BlackBerry. The Holiday Inn's door key app uses an encrypted audio code to open the door, which is digitally disposed when you check out.

The system is in limited testing now, but might see widespread adoption next year, when the future will presumably have fully arrived. [via Download Squad]
