Photo by CoCreatr A QR Code (short for "Quick Response") is a barcode that contains data that can be read by a phone's camera. Most smartphones come equipped with software that allows them to download a QR Code reader. Once you download a reader, the phone's camera acts like a scanner, allowing it to "read" the barcode. These codes, once scanned by your phone, can provide you with a URL, contact information, SMS, or similar links to information right on your phone. Think of it as a black and white link, or a heavily pixelated one.
