QR Code Barcode Overview QR Code is a very efficient, two-dimensional (2D) barcode symbology that uses a small area of square modules with a unique perimeter pattern, which helps the barcode scanner determine cell locations and decode the QR Code symbol. Characters, numbers, text and actual bytes of data may be encoded, including Unicode characters and images. ID Automation's implementation of QR Code is based on the ISO/IEC 18004:2006 standard.
