I’m old enough to remember when credit cards were actually “charga-plates,” actual pieces of metal with raised letters that you’d hand to a department store clerk as payment. He/she would then put the plate in a small machine and do that “shwack-schwak” thing to imprint your account information onto a carbon-type invoice. Later we went to plastic, but still with the raised numbers. And later still, at least Europe began using smartcards. Well, throw them all away. Now there is Card 2.0, a piece of plastic the same dimensions as a current credit card, but imbedded with electronics of a very sophisticated nature. First, the card can memorize several account numbers, and it will re-magnetize the magstripe as you turn them on and off. Second, you can turn on-off the electronic display of the account numbers to maintain your privacy. Watch the short demo video and see if you say, “Wow!”
