Around 1993 my husband Michael was at a show. During the show, a man in his mid 20s started talking with Michael and told him the following story.
It seems this man, lets call him Dave, was a member of the military. Dave was shopping at the Military PX (their general store) and he was checking out. It was right before closing because everyone was trying to get out of the store quickly and was hurried. A man in front, let's call him Jim, checked out all of his items, about two grocery bags full. Without thinking about it, after checking the last item Jim ran his hand over the scanner - AND IT REGISTERED!!!!! It came up on the screen. The screen treated his hand as a debit card!!!
Jim realised he had messed up. He was supposed to be in another check-out line where people were not meant to see what happened.
The cashier was very flustered. She made Jim back out the transaction and made him pay the normal way.
Dave then checked out also, and outside asked Jim some questions. Jim told Dave that it was a government program. He and about two hundred other people volunteered to accept a chip implant in their hand for payment purposes. He was paid $20,000-$30,000 (can't remember which) for this!!! It worked only at the Military PX.
So, you can see, 'they' are already getting systems in place for the cashless society they dream of.
