QR Codes

A QR Code is a matrix barcode readable by mobile phones with a camera, and smartphones. The code consists of black modules arranged in a square pattern on a white background. QR is the acronym for Quick Response, as the code allows its contents to be decoded at high speed.

QR Codes can be used to display text to the user, to add a vCard contact to the user’s device, to open a URI or to compose a text message or email.
