What initially started out as a barcode to keep track of vehicles, the QR Code has now become a staple in today’s mobile phone industry. Developed by Denso in 1994, the QR Code or Quick Response Code is a two-dimensional matrix barcode which consists of black square dots or modules arranged in a pattern and placed on a white backdrop. The code increased in popularity thanks to its huge storage capacity compared to the regular UPC barcodes and also because machines are able to read it quickly.

Popular Uses Of The QR Code

Online Marketing

Before QR codes were created, businesses had to make people remember their website’s URL to help drive in traffic.
