However, over the past ten years, quasi-standards have been established that define how certain types of data have to be encoded. This is very different from codes like EAN 13 where the data format and content are regulated by a standards body (GS1). How the content is interpreted depends entirely on the scanner or scanner app. QR codes only encode textual content and are indifferent to the actual semantic meaning of the data.
QR FACTORY GENERATOR
The respective barcode generator will select the compaction mode that results in the smallest posible symbol it is common to switch between modes within a QR symbol for mixed content.
Intended for use in manufacturing and part tracking by the auto industry, QR's design prioritized fast and reliable scanning over smaller size. Larger codes also feature one or more alignment patterns. Those patterns are quite large, so the code needs more space than other 2D symbologies, at least with small amounts of data. The code is easily recognized by the characteristic three finder patterns in the corners of the symbol: QR is a two-dimensional or matrix code that can encode up to 4,000 characters or 7,000 digits.
