Types of QR Codes
There are two types of QR codes depending on the way they store information, namely static QR codes and dynamic QR codes.
- Static QR Code: As the name says, a static QR code can’t be changed. It is fixed. This means that once a static QR code is created, it can’t be edited. Also, these codes grow in complexity and size if the amount of information stored in them is increased. Thus, they tend to slow down a bit. It is advisable to use static QR codes for one-time use like serial number or check-in information.
- Dynamic QR Code: A dynamic QR code can be changed even after creation. In other words, you can edit or make changes to this QR code as many times as needed. This is because the information stored in these QR codes is in the form of a URL. Upon scanning, the user is simply redirected to this URL where the required information can be found. This is why they are way faster than static QR codes. It is advisable to use dynamic QR codes for tracking purposes and product labels.

Ever opened WhatsApp on your PC or Laptop by scanning a black square box that seems to be colored unevenly in pixels? Well, that square box is nothing but a QR code. QR code is a 2-Dimensional bar code in the form of a matrix. It is like a label that can be read by machines to fetch the needed information they contain. Just like a barcode, which is 1-dimensional, is read using a scanner, a QR code can be scanned using our phones.
