What is the difference between a barcode and a QR code?
The main difference between barcodes and QR codes is one of physical dimensions. Barcodes can be scanned in a line. QR codes, on the other hand, add another dimension from which information can be written and scanned. Instead of a single line, these labels can be read both vertically and horizontally.
