Abstract
Techniques for calibrating measuring devices are provided. A universal serial bus (USB) drive is inserted into a USB port on a device of a checkout system. A key in the USB drive initiates a calibration sequence on one or more weighing devices (measuring devices) of the checkout system. Audit information is captured during the calibration and usage of the weighing devices. When a command is recognized to communicate the audit information, the audit information is audibly communicated from speakers associated with the checkout system.
