Which is why you need cards that *you* own/control and so can then download
to your PC an audit log of when you did touch in/out.

The non repudiation problem again. This is why I won't do e-banking,
if I claim that I paid something and the bank then decides that I didn't
I get um-stuck for non payment/... I have asked the bank how to cope
with this - their only suggestion is for me to print out the web page
showing that I did it!
Until non repudiation is implemented I shall stick to paying my bills
over the counter - they seem to accept the little purple stamp as 100% proof
that something happened.

Non repudiation is quite easy to do: they just send a short message confirming
the transaction that is digitally signed by them - only they can sign it, so QED.

I suspect that they don't want to 'cos they could then be held liable for their
mistakes.
