Micro QR Code (Micro Quick Response Code)

Also known as Denso Micro Barcode, Micro QRCode, Micro Quick Response Code, Micro QRCode Model 2, JIS X 0510, ISO/IEC18004

This Barcode Symbology is supported by the following Neodynamic products:

Overview

Micro QR Code (Micro Quick Response Code) QR Code is a kind of 2-D (two-dimensional) symbology developed by Denso Wave (a division of Denso Corporation at the time) and released in 1994 with the primary aim of being a symbol that is easily interpreted by scanner equipment. Micro QR Code is a very small QR Code barcode that fits applications that require a smaller space and use smaller amounts of data, such as ID of printed circuit boards and electronics parts, etc.

Micro QR Code is capable of handling all types of data, such as numeric and alphabetic characters, Kanji, Kana, Hiragana, symbols, binary, and control codes.

The symbol versions of Micro QR Code range from Version 1 to Version 4. Each version has a different module configuration or number of modules (the module refers to the black and white dots that make up Micro QR Code). "Module configuration" refers to the number of modules contained in a symbol, commencing with Version 1 (11 x 11 modules) up to Version 4 (17 x 17 modules). Each higher version number comprises 2 additional modules per side. Each Micro QR Code symbol version has the maximum data capacity according to the amount of data, character type and error correction level.

Micro QR Code is not capable of storing much data (maximum 35 numeric characters). However, because it can store data for each symbol size more efficiently than QR Code, the size of Micro QR Code symbols does not significantly increase, even though the amount of data is increased.

Maximum Data Capacity for each Micro QR Code Symbol Version:

Symbol version Number of modules Error correction level Numeric Alphanumeric Binary Kanji
M1 11 - 5 - - -
M2 13 L 10 6 - -
M 8 5 - -
M3 15 L 23 14 9 6
M 18 11 7 4
M4 17 L 35 21 15 9
M 30 18 13 8
Q 21 13 9 5
