What Is A QR Code?
A QR Code (Quick Response Code) is a 2D matrix barcode that can store up to 4,296 alphanumeric or 7,089 numeric characters. It’s generated by inputting data into a QR code generator, which then creates a scannable code. Most modern smartphones have built-in QR scanners in their cameras, while older devices can use free scanner apps across all platforms.
Types of QR Codes
Static : Store fixed information directly in the code, unable to be edited later.
Dynamic : Link to a database, allowing users to update the destination URL. They also offer basic scan analytics.
