The input data is always analyzed and the appropriate encoding mode is chosen automatically.
Mode switching is done as required to produce the most efficient encoding.

This 2D symbology is a small variant of QR-Code with a reduced number of overhead modules and
a restricted range of sizes and was developed for fast readability (QR = Quick Response) by Denso.
The symbol size adjusts automatically depending on input data.

Micro QR-Code has 4 different symbol sizes (M1-M4). The smallest version (=size) M1 is restricted
to numeric data and error detection, M2 may contain also alphanumeric values, and M3 and M4
may use the whole range of the QR-Code character sets (bytes, Kanji).

The maximum amount of data is 35 numeric, 21 alphanumeric, 15 byte, or 9 Kanji characters, in
conjunction with the lowest error correction level.

This (stacked) 2D symbology was invented by Symbol Technologies. It is used to encode large
quantities of data. It is the de-facto 2D standard symbology in the automotive industry.

The symbol is divided into rows and columns. TEC-IT software adjusts the size automatically
depending on the amount of input data. A data density of up to 900 characters per square inch is
possible.

The input data is always analyzed and the appropriate encoding mode is chosen automatically.
Mode switching is done as required to produce the most efficient encoding.
