According to Wikipedia, QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed in Japan for the automotive industry. A barcode is a machine-readable optical label that contains information about the item to which it is attached. QR codes are tiny black and white squiggle-like barcodes embedded on any item the owner wants people to find more information about.
Let’s say I bought a packaged item from the grocery store and a QR code is placed on the seal, If I use a barcode scanner to scan it I will find further information the manufactures want me to see, be it their website, address or any information whatsoever as long as it is embedded in the code. QR code is now widely adopted in industries, companies and stores as it can be used as a form of marketing campaign, most business cards I see nowadays have QR codes embedded in them.
