Many of us in the West have long been looking lustily at Japan's mobile phone e-cash systems with little hope of getting anything similar soon, so forgive us if it seems a little unfair to report an even more exciting development in m-commerce.

As you might have guessed, the amount of money being sent is added to one DoCoMo user's phone bill and credited to the other's bank account.

So far, that's all that has been revealed, but we can see this kind of mobile micropayment doing for phone users what PayPal did for small merchants on the web.
