i'll look into it now, if im honest this is the first i've heard of it. My knowledge lies in atm fraud and counterfeit money (though i have not participated and do not condone any of the above) this is completely new to me. What are the advantages of it, and can you set the price to what you want? If a receipt printer could be acquired, you could in theory say the item is worth more than it is on the shelf and return it complete with a receipt. All hypothetically of course.
