During an inspection discrete checkpoints provide data to a portable reader, enabling a record to be generated identifying each checkpoint visited during an inspection. At least one checkpoint associated with the inspection will convey ancillary data to the portable device, either in lieu of, or in addition to, a checkpoint ID uniquely identifying a location or component inspected. The ID is not ancillary data, because the only function of the ID is to verify that an inspector was present at a particular location or component. In contrast, ancillary data are data that have an additional utility. For example, a sensor may be disposed in proximity of the component or location to be inspected. Data collected by such a sensor represents ancillary data, because such data does more than uniquely identify a particular location or component that was visited during an inspection.
