What if we just forget about change? One of the neat things about ecash is that it allows for coins of (fairly) arbitrary values. We can use this to our advantage, since we can guarantee that we can make a single payment of any value with a small number of coins.
The Visa stored-value cards now in Atlanta don't do this, but as a simplifying measure most vendors in the Olympic Village (and many within the downtown venue ring) have rounded prices to the nearest US$. The precedent's been set. -Paul -- Paul Robichaux LJL Enterprises, Inc. paul@ljl.com Be a cryptography user. Ask me how.
