QR stands for Quick Response, as QR codes can be read quickly by a smartphone. They contain information that can be read by a phone’s camera. QR codes are more convenient than standard barcodes because they’re able to contain much more data including links, geographical coordinates, and text.

With cryptocurrencies, QR codes are used for sharing wallet addresses.
