1. An adapter for use between a point of sale terminal and a commercial wireless device, said adapter comprising:
- a physical interface for mechanically connecting said adapter to at least one specific commercial wireless device;
a short range wireless protocol module for receiving communication from said point of sale terminal;
a circuit for sending control signals through said physical interface to control said wireless device in response to received ones of said short range wireless communications; and
a circuit for receiving power from said commercial wireless device wherein said circuit stores power derived from data sent from said commercial wireless device.

Abstract
A short range wireless protocol is established to/from a processing device, such as a point of sale terminal. Adapters are designed for mating with different ones of commercially available communicating devices (host) using the public switched network. The adapters are arranged to communicate with the host using the host protocol and with the processing device using the established, short range wireless protocol. In one embodiment, power is derived at the adapter using parasitic power from the communication link.

13. The method of clearing a credit transaction, said method comprising the steps of:
-
accepting transaction information at a point of sale terminal; establishing a wireless communication connection between said point of sale terminal and a communicating device located remotely from said point of sale terminal, said wireless connection using a short range protocol different from the protocol used by said remotely located communicating device; accepting said short range wireless protocol at an adapter temporarily physically mated to said remotely located communicating device, said adapter serving to convert between said different protocols; and generating extraneous data at said remotely located communicating device, said extraneous data used for delivering power to said adapter. - View Dependent Claims (14)
