Mondex keeps their protocols confidential. Not so good to establish
trust in the system.
I also heart _rumours_, that several things went wrong in their
current field-test. Reminds me that I should go after these rumors.
Additionally several banks begin to establish their own e-cash
systems. E.g. in Germany from 1st January 1997 on nearly every
bank-customer will have an electronic-purse.
The main problem with e-cash proposed by Chaum et al. is that current
SmartCards are not powerful enough to handle the needed computation in
a timely fashion.
The purse proposed by the german banks you have a simple counter on
your SmartCard. With this system you _must_ have identification of
payer and payee to clear malfunctions or frauds by either party.
Bye!
