How are QR Codes read?
QR Codes can be read using barcode scanners and software however any smartphone / cell phone that has a camera and a decoding app can also decode them. The increase in popularity is most likely due to ease of decoding with a phone. The phone simply takes a picture of the QR code and then the phone is able to distinguish the light and dark patterns which is translated using an algorithm to present the text encoded by the person that made the QR code. If the decoding text is a web link phones with internet access can automatically be directed to the website depending on the decoding app.
