If the phrase “static QR code” is stressing you out, don’t let it. And sometimes there’s so much information encoded in it, it can’t scan or scans extremely slowly. Sometimes they’re used to store quite a bit of information. From QR codes in healthcare to QR code food uses. This can also cause QR code scanners to fail. Think of light blue modules over a dark blue background. There isn’t enough contrast between background and foreground. Likewise, the QR code may have lighter colors over a darker background, but the difference between the two colors isn’t big enough. But any time a QR code flips that dynamic and places lighter squares over a darker background, it can trip some readers up. That is, in turn, what most QR code scanners were designed to read. QR codes were originally designed to have square black modules on a white background. Often that means getting creative with their custom QR code’s color or contrast. That leads them to some QR code marketing or QR code tracking experimentation for the sake of aesthetic unity with the rest of their branding. Color and ContrastĪ lot of businesses and brands value form over function.
