Abstract
A calibration process is started by a capacitive input variation when a capacitive button is pressed on a barcode reader. Or, the calibration process is started by the barcode reader scanning a configuration label or special label or barcode after the capacitive button on the barcode reader is inoperative. The calibration process realigns the input and the threshold to correctly configure the capacitive button.
