Want to try it? PayEye opened its first U.S. office in East Lansing this week, as well as their launch in local businesses. The technology uses a scan of your iris, which PayEye says is five times more unique than a fingerprint. What you do is set up your profile on their app, and then your eye will be ready to pay to bill. Right now, the technology is being used at mid-Michigan businesses Barrio, Kellie’s Consignments, 6 Lounge and Jet Fitness. For more information, go here.
