In a similar vein, Barclays customers will tap their PIN into a keypad mounted on the card which will create a range of security ciphers.
The codes will be generated at a timed interval by a tiny clock and appear next to the signature strip.
This is pretty much what the card will look like I think.
Actually, I’m being a little naughty here. That picture is actually of the Visa SuperSmartCard, produced by Toshiba back in 1986, but I imagine the Barclays one will work in pretty much the same way.
