mobile operator transports a portable tool (14) to a plurality of
locations where a site-specific activity is to be conducted. The portable
tool includes a location detection device (32). Processing of data using
the portable tool is enabled only when the portable tool is located

device. In various embodiments, the enabled site-specific activity may
include data recordation, data transmission, data reception, data
processing, and/or the display of a data entry form.
