Creating QR Codes:
What is a QR Code?
A quick response (QR) code is a type of barcode that can be read easily by a digital device and which stores information as a series of pixels in a square-shaped grid. QR codes are frequently used to track information about products in a supply chain and often used in marketing and advertising campaigns.
How Does It Work?
The patterns within QR codes represent binary codes that can be interpreted to reveal the code's data. A QR reader can identify a standard QR code based on the three large squares outside the QR code. ... It then groups grid squares to create larger patterns.
