What is a QR Code?

Last updated on June 12, 2023

Quick response or QR, is a type of barcode that can store a multitude of information. The obvious difference between a QR Code and Barcode is its appearance. A QR Code is always in the shape of a square and contains smaller, even blocks similar to Tetris. A Barcode, on the other hand, has vertical bars in different thicknesses and is often accompanied by a serial number.
