There are several practical applications for a QR code scanner. This flexibility in QR code scanner use is due in part to the flexibility that can be found in QR codes.
Within the realm of standard QR codes, there are dynamic and standard QR codes. With a static QR code, once you select the content, it can’t be changed. Once you say that a QR code is linked to a particular application or website, you can’t then later reassign it to another link or website.
With a dynamic QR code, you can change the content it is linked to as frequently as you want. This is why it is referred to as recyclable QR code. You don’t have to keep printing the code over and over again. For example, there may be a QR code that is hung at a coffee shop or other restaurant that is frequented by customers. The QR code directs users to the website’s of bands that will be performing at the venue. Since there is a new band every week, the QR code needs to redirect users to a different band’s website each week. This can be done with a dynamic QR code.
QR codes are not impervious to damage. If a QR code gets slightly damaged or partly obscured, it is still usable because it has an error correction feature. Within the code, there are four levels. Each level can sustain a set amount of damage. All this information determines the actual size of the QR code once it is printed.
