The Mark revisited

CounterIn today's link, we see a seemingly innocuous story about blind people needing to be able to use currency unaided. So why not make our currency (speaking USA here) more distinguishable to a blind person?

Cost, of course. And even signing a credit card slip could be pretty hard for a totally sightless person.

But what if a device could be used to transact business that would be equally easy regardless of whether the buyer could see or not?

Such a device exists--the RFID microchip.

Stand by, folks.
