Electronic currency using SIM Access Profile

You might remember an ad campaign in which a woman approaches a soft drink vending machine alongside a young male executive. The executive rummages through his pants pocket to find, to his dismay, that he has no change to purchase a cool drink on a hot afternoon. The woman then pulls out her cell phone, presses a few buttons, and a soda can drops down from the vending machine. The ad was meant to show a future of a seamless, interactive world. The SIM Access Profile, released by the Bluetooth Special Interest Group (SIG), makes such transactions a reality, allowing a consumer to use a cellular device to obtain, for example, a 50-cent soft drink without spending 25 cents on a cell phone airtime charge.
