“For more information, please scan the QR Code shown below” – You must have seen this particular phrase along with a square-shaped image printed in pamphlets, book covers, business cards, etc. If that’s the case, then you've seen a Quick Response or QR Code, a 2D image that is almost similar to a barcode. The key difference between the two is the capacity to handle information. While barcodes could only interact with a few bytes of information, QR codes can handle more and could even store more complex and varied forms of data. The data could be in the form of hyperlinks, text, images, and even videos. Also, QR codes are easier to decode compared to barcodes because all it takes is just a QR code scan from a smartphone and afterwards, the coded digital information would then be revealed.
