I carry the reader with me when I go to gun shows as I've sold a few things walking around that I probably couldn't i it had been cash only.I considered using them for a bit - until I found this in their agreement:

MMMMMMMM, John Hot StewSigasaurus and I made it out to the show early this AM. Good show, crowded in some areas, other than that there was room to move about... I picked up a new Colt mag for my RIA 1911, and a cheap-o Stiletto knife for the Boss Lady to throw in her hand bag. Sigasaurus picked up a couple springs for his AR builds, and a Stiletto knife too.
After milling about for a couple hrs, we made our way to John's Famous Stew for a bite to eat... +1000 for the Supreme Tenderloin, mighty tasty
