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...
