Digital cash announced today by UK bank.

Apparently the Natwest Bank (or some spoonerism thereof) announced today that they were releasing digital cash in the form of some sort of smartcard. I have no more details - does anyone else? Primarily I'm interested in knowing if it's *anonymous* digital cash - knowing our govt, I suspect it's unlikely to be. Any new opportunities to track the masses are always gratefully received by the powers that be... G
