30 Interesting Facts about QR Codes

Barcodes have been in use in retail since 1974 when the first barcode in retail was scanned in an Ohio (USA) retail store. IBM was behind the development of this barcode scanner. Barcodes have greatly simplified the identification of retail items and simplified inventory management and stockkeeping in retail stores, allowing for a smooth shopping experience and high profit. Barcoding allows employees to quickly scan a barcode on a product label and save the information on a computer screen, without manually entering the same. It simplified POS (Point of Sale) and allowed customers to quickly pay for their items and check out.

However, a barcode is limited by its design in terms of data it could store and the scanning, which has to be a clear line of sight and requires specific alignment. Many barcode scans also failed. And now we have QR Codes, a better version of barcodes. QR Codes are destined to replace barcodes for good.

Let’s see some of the interestingly cool facts about QR Codes, which might be unknown to many:

Interesting Facts about QR Codes

1. The QR code, short for Quick Response code, was first developed in 1994 by a Japanese company called Denso Wave, a subsidiary of Toyota, to track vehicles during the manufacturing process. ‘QR’ reflects its purpose of providing quick access to information when scanned.

2. QR code was invented by Japanese engineer Masahiro Hara who had previously worked with barcodes. He was inspired by the black-and-white patterns of the popular board game ‘GO’.

3. DENSO WAVE made the specifications of the QR Code publicly available, allowing anyone to use it freely. Although DENSO WAVE retained the patent rights, they decided not to exercise them, allowing the QR Code to be used by as many people as possible.

4. The QR code was designed to be a two-dimensional barcode that could store more information than traditional barcodes, such as URLs, text, and other data. The versatility makes QR Codes useful in a wide range of applications.

5. QR Codes can contain around 3K bits of data which is around 7000 characters, far more than barcodes.
