E-wallets will be like mobile phones themselves. We didn’t know we needed them until we have them. What do people care about the most? Here’s a list of customers’ requirements we’ve discovered, in rough priority order:

1. Don’t let my account information be seen or used by anyone; even the person or company I’m paying. Use some kind of proxy for my actual credit cards and bank account.
2. If I lose my phone, I don’t want my information to be compromised or able to be compromised, and I want it backed up so I don’t lose anything.
3. Let me purchase little things (a can of soda) or big things (a computer) without penalizing me, or the merchant, with high transaction or processing fees.
4. Let me manage my spending, see where my money is going, and feel sure I’m always getting the best deal.
5. Don’t lock me into a single mobile phone network, mobile phone, or e-wallet; Let me migrate seamlessly from one to another
