I've talked about symbols before here
I saw an article today on RFID credit cards, "In credit cards, it allows customers to swipe the cards past readers in such establishments as McDonald's restaurants and CVS pharmacies, making for quick and easy transactions. Visa says it has distributed over 6 million "contactless" cards worldwide, and the UMass study estimates that at least 20 million exist, with the total growing rapidly." I believe that RFID chips used in this manner are just a short step away from having an RFID chip put in to your hand for swiping.
However it was the logo itself that I found interesting and after the video I started looking in to it more and of course I couldn't help myself.
As always take it however you want, I just found it fun to do. (Click image to see larger version)
I think I could have gone on and on with these in to other symbols and meanings but decided to leave as that.
