Short for Quick Response Code, this looks like a square barcode made up of pixels, usually black and white, that can be scanned by a smart device camera. When scanned, the pixels are translated into readable data such as a URL that directs you to a website, a phone number or other types of text. It's a quick way to access information. QR codes are used at some cafes and restaurants instead of paper menus to order and pay without having to line up, or in eScripts or electronic prescriptions as an alternative to paper prescriptions.
