摘要

A method of conducting commerce within a portable, wireless computing device can include storing an identifier specifying a cellular communications channel and receiving a user input specifying financial transaction information. The identifier and the financial transaction information can be provided to a receiving device over a short range, wireless communications link to initiate the financial transaction. An authorization code can be received via the cellular communications channel specified by the identifier. The authorization code can indicate whether the financial transaction was approved.
