What is QR Code (QR Code)?
A QR code is a type of barcode that can be easily read by a digital device and stores information as a series of pixels in a square grid.
QR codes are square-shaped matrices of dark or light pixels used to encode and quickly retrieve data using computing devices.
It can store approximately 7,000 digits or approximately 4,000 characters, including QR codes, punctuation, and special characters. It can also encode information such as phone numbers or internet addresses.
The layout of each QR code changes depending on the information it contains, and this changes the layout of its black modules.
Static and Dynamic QR Codes
QR codes differ in design depending on the data and function being encoded and can basically be categorized in two ways: static and dynamic.
Once a static data matrix is created, it cannot be changed. This is ideal for generating data matrixes for an event in bulk. A good example of a static QR code would be for your Wi-Fi password.
Dynamic QR codes allow you to change and edit the code as much as you want.
When the code is scanned, it redirects you to the URL contained in it. These codes give you the freedom to package your design, such as adding contrasting colors. They also have the ability to monitor and measure ad statistics.
