It isn’t an instant reset if you’re going to give out the card for examination or allow them to sign
it. Also, the signing of the card screams suspicion.
The gimmick is well made and should
last. The concept is interesting and if you’re getting it for a one off (leave out the signed card
part) I think it would be worth your time. I was trying to use it for walk around and was really
hoping it would be more of an instant reset.
