All About QR Codes: What They Are, How They Work, and Why You Should Use Them
What is a QR Code ?
A QR Code (Quick Response Code) is a square-shaped, 2D barcode that stores much more information than a traditional barcode. You can scan it with a smartphone or tablet to instantly access a website, file, contact info, video, etc.

Types of QR Codes
Two main types :
