What does QR Code mean?
You can think of a QR code as the 21st century equivalent of the rectangular bar codes found on pretty much everything you buy in stores.
The difference is that a QR code is square and it holds a lot more information than a bar code. QR codes can be scanned by smart phones and many merchants that accept cryptocurrencies will permit you to simply scan a QR code and pay with the click of a button. It’s so much faster than waiting in line at the store.
