Hänsler told CNN that although the service will remain free for users, ultimately aka-aki intends to sell profile space to commercial ventures. "A shop or brand can have a profile at aka-aki and you could 'meet' a shop, or a shop could tell who is passing it every morning and maybe offer that person a voucher for something, or tell them when they have special offers," he said.

Aka-aki is currently focused on Bluetooth technology, because it's so widespread in cell phones, but the GPS technology in Apple's iPhone is even more exciting, because of its ability to pinpoint the position of its users outdoors, with the iPhone's wi-fi detection performing a similar function indoors.
