Mariott is testing a system that will be very helpful for all of the business travelers out there. The new system allows room check-in, room changes, rate confirmation and welcome information all via smartphone. No need to wait in endless lines so some scummy kid can give you a key. Complete all of the information digitally on your smartphone and an automatic dispenser will shoot out your keys. Only one hotel in Redmond, Washington is currently testing the system.
