Auditing shelf space of an outlet of a retailer using a device comprising: a computer, a camera, a global positioning system receiver and a repository. The device is authenticated using the time and date of the audit, and a location of the audit at the outlet of the retailer. Once the device is authenticated, images of displays within the outlet and audit information relating to the display and the outlet of the retailer are captured and audit information is embedded into the captured image. The captured image is encrypted and sent to a remote computer of a checker company for a compliance check.
