Best Practice for QR Codes
This week The Barcode News included an article in their newsletter outlining 10 top tips for using QR codes effectively. We thought this was so good we’re linking to it here. Their tips include respecting the margin around the code; using short urls; and making sure they’re big enough (though not too big – .e.g 12ft!). One thing that they don’t mention that we would definitely add is to avoid putting unnecessary graphics in the middle of QR codes as these tend to compromise the readability of the code and remove any of the code’s own inbuilt tolerance to withstand poor reading. Putting a picture in the middle of a code effectively means that a higher percentage of people trying to read it will be unsuccessful. Furthermore, avoid replacing the cells in the QR code with icons as these alter the balance of black and white in the code and also have a detrimental effect on their readability.
