Some older devices may require a particular app to read QR codes – these apps are readily available on the Apple App Store and Google Play. Initial uptake of the idea was slow; however, in 2002, the first mobile phones containing built-in QR readers were marketed in Japan. The use of smartphones led to an increase in the number of companies using QR codes. And much more – a company in the UK called QR Memories even creates QR codes for use on gravestones, allowing people to scan the code to read more about that deceased person’s life . A QR code is a type of barcode that can be read easily by a digital device and which stores information as a series of pixels in a square-shaped grid. More recently, they have played a key role in helping to trace coronavirus exposure and slow the spread of the virus.
The QR code scanner in your phone’s camera recognizes the three position markers in the QR code. With a sufficient quiet area, your scanner is now aware of where the edges of the QR code are. In the case of QR codes, numeric and alphanumeric characters, bytes, and kanji convert into a unique two-dimensional arrangement of squares.

At Honeywell, we designed the Granit series barcode scanners with scan glass that is twice as far back and smaller than competitive models, which has made it almost resistant to damage. Laser barcode scanners were the original 1D barcode scanner. They were fast and efficient but were limited to reading 1D barcodes (e.g., Code 39, Code 128, UPC) and were historically prone to failure due to the moving parts. Sometimes no-read results from the physical position of the scanner. Barcode scanners have minimum/maximum distances that allow the scanner to adequately focus the code/symbol clearly. If you are too close or too far away for your scanner’s optical range, you will have a no-read.
