Abstract
A barcode reader for capturing a barcode connected to a moving carrier is proposed having at least one optical barcode detector for at least one-dimensional capture of information modules of the barcode. The barcode reader furthermore comprises at least one optical clock track detector for capturing clock track modules of a clock track of the barcode and at least one optical reference detector for capturing at least one item of reference information of the barcode. The barcode reader is configured to determine a direction of movement of the carrier from at least one signal from the clock track detector and at least one signal from the reference detector.
