QR Codes: Not for Human Eyes
This communication was not meant for human eyes, or even alien eyes. It is an attempt to communicate directly with your smartphone. Cameras on many smartphones can image this Quick Response, or QR, code. Common applications can then tell you what it means, often revealing a website address. QR codes are two-dimensional analogs of bar codes.
