Touchatag

Touchatag is a little device that lets you use your phone to do things like open doors or pay for things. It's like your own personal tag that you can keep in your pocket. You can set it up to do different things, like unlock your car door when you wave it in front of your car, or buy something from a store without having to take out your wallet. To use it, you just wave the tag in front of the device and it will do whatever you programmed it to do.
