It was invented by the Toyota Japans Subsidiary Denso in 1994 to accurately track the vehicles and spare parts; this type of barcode accurately encodes kanji, kana, and alphanumeric characters.  Kana print alphabet of Japanese and are the cursive from, and the entire words are represented by Kanji. Kanji may be standalone and can be connected with other Kanji or Kana to form words of different types.

These codes can be read in all directions while as barcodes read only in one direction hence becomes acceptable for most of the applications. QR codes store huge amount of data from texts to websites to emails.
