Before the introduction of QR codes, 2D bar codes were used, but they had some limitations. It used to have one or more circles/squares in the middle of the bar code. It gives the position of any scanner to scan circle/square. The biggest problem with this type of mid-position QR code was that whenever the QR codes were scanned one by one or placed together in bulk, the scanner would get distracted. Used to scan two codes as one.

If the QR code was discolored or scratched, the scanner could not scan it. Due to which there was a big problem in commercial purchases or money transfers. Due to which Hara Masahiro, an engineer at Denso Wave Company, invented the QR code in Japan in 1994. Which is considered the most accurate in high speed scanning with secure scanning. Today we all use the same QR code.

Only 3 squares that appear in QR code are responsible for high speed and secure scanning of any QR code. This tells the square scanner the exact position of any QR code. The small square code on the fourth side tells any scanner the alignment of the QR code. Whether the QR code is placed upright or inverted or diagonally.

If multiple QR codes are put together, these three sections allow the scanner to scan all these QR codes separately in a very short time. The middle pattern of QR code stores all the details of any product like cost, category or other information related to that product. From your Aadhar card to branding of any product, you will get QR codes. Nowadays QR code is considered safe even in money transfer.
