1. A method of operating a portable computing device that is operative to execute an application program stored therein and to wirelessly communicate with data terminal equipment at a remote site with respect to execution of said application program, said method comprising the steps of:

  • (a) coupling said portable computing device as an auxiliary data input to a wireless emission tag that is operative to generate wireless spread spectrum emissions monitored at a plurality of spaced apart tag emission readers of a geolocation system, outputs of said tag emission readers being processed to geolocate said tag and thereby said portable computing device by detecting first-to-arrive spread spectrum emissions and performing time-of-arrival differentiation of the detected first-to-arrive emissions;

    (b) incorporating transaction data generated by said portable computing device in association with its execution of said application program into said wireless emissions from said wireless emission tag; and

    (c) coupling said transaction data from said geolocation system to said data terminal equipment at said remote site.
