SnowShoe

SnowShoe is a Madison, WI startup that makes the SnowShoe Stamp: an insanely intuitive, inexpensive and indestructible way for smartphones to authenticate real-world interactions. A simple touch of the SnowShoe Stamp to the screen of a person's smartphone proves that the phone's owner is in a specific location, at a specific time, and is interacting with a person or system in an authenticated way.
