   en.wikipedia.org/wiki/QR_Code

   The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [6] [7] [8] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [9] the pattern of the position detection markers was determined by finding the least-used sequence of ...

   A wide variety of different tracking technologies exist, including QR codes, Natural features, 3D and Face Tracking. As all these tracking types use different algorithms and technologies, the definition of a Trackable is abstracted and split into two parts, a Tracker and its associated Trackables. A Tracker describes the technology (or ...

5. Rectangular Micro QR Code - Wikipedia

   Rectangular Micro QR Code (also known as rMQR Code) is two-dimensional (2D) matrix barcode invented and standardized in 2022 [1] by Denso Wave as ISO/IEC 23941. [ 2 ] rMQR Code is designed as a rectangular variation of QR code and has the same parameters and applications as original QR code.

6. Track and trace - Wikipedia

   en.wikipedia.org/wiki/Track_and_trace

   RFID is synonymous with track-and-trace solutions, and has a critical role to play in supply chains. RFID is a code-carrying technology, and can be used in place of a barcode to enable non-line of sight-reading. Deployment of RFID was earlier inhibited by cost limitations but the usage is now increasing.

7. Mobile tagging - Wikipedia

   On the other hand, there are several readers which were created to read out non-proprietary code, these 'open source codes' are the most used for Optical Reading with Mobile like the QR Code and the Data Matrix. However, a QR code is always 60% larger than a DataMatrix code and this tends to mean that DM is the primary code used in packaging ...
