US Patent 7127236 Micropayment financial transaction process utilizing wireless network processing

A MicroAdapter device enables payment transactions to be effected through a purchaser's personal trusted device (PTD) without relying upon tokens or prepayment cards. In one embodiment, the MicroAdapter includes a transceiver configured to receive a purchase signal from the PTD including order and payment information. In response, the MicroAdapter communicates via wireless telephony with a transaction authorizer to receive authorization for effectuating the purchase transaction. The MicroAdapter may be particularly suited to effectuate micropayment transactions authorized by a Billing On Behalf of Others (BOBO) program administered through a wireless carrier/ISP or third party.
