5 stars: I'm satisfied with the nature of the program. It's a quick way for someone to check your QR code to see if it's valid. It doesn't store your info, or send it off the phone. It just checks the cryptographic signature of the data in the QR code, and shows your name and date of birth to be cross-checked with your id.
