Dave Birch describes/links to this posting that explain how to do fraud via m-payment etc:
This is how it works: You buy a stored value card for X amount of dollars and a prepaid mobile phone. Next, you register with the m-payment service provider using a free anonymous e-mail account, your prepaid mobile phone number and the money on the stored value card. Using your mobile phone, you log on to the m-payment service provider and give them the number of the mobile phone to which you wish to transfer the funds from your stored value card. The m-payment service provider sends a message to the receiver's phone number asking where to transfer the money. The recipient can request the transfer to his stored value card and withdraw the funds from any ATM.
