Abstract

A system for registering a sensing device with a relay device, the relay allowing the sensing device to communicate with a computer system. The registration is performed using a registration form, the registration form having disposed thereon or therein information relating to at least one interactive element, and coded data at least partially indicative of the interactive element, at least some of the coded data being coincident with the information such that when a sensing device is placed in an operative position relative to the information, the sensing device senses the coded data and generates the indicating data using the sensed coded data. The indicating data is at least partially indicative of the sensing device identifier and the at least one interactive element so that when it is received by a computer system, the computer system can determine the at least one interactive element and cause registration of the sensing device using the interactive element.
