ABSTRACT:
An optical information reader for settling a commercial transaction reads and decodes with certainty a quick response (QR) code displayed on a buyer's mobile telephone display. A QR code11is displayed on the display a plurality of times at a prescribed time interval. The QR code is rotated by 90° every time. Therefore, a part of the QR code which could not have been decoded due to a mirror reflection, stains or scratches on the display can be decoded at the second, third or fourth display, because the QR code11is displayed four times at different angles.
