2. Nah, just kidding!
According to Wikipedia,
QR code (abbreviated from Quick Response Code) is the trademark for a type
of matrix barcode (or two-dimensional barcode) first designed for the
automotive industry in Japan. A barcode is an optically machine-readable
label that is attached to an item and that records information related to that
item. The information encoded by a QR code may be made up of four
standardized types ("modes") of data (numeric, alphanumeric, byte / binary,
Kanji) or, through supported extensions, virtually any type of data.
The QR Code system has become popular outside the automotive industry
due to its fast readability and greater storage capacity compared to standard
UPC barcodes. Applications include product tracking, item identification, time
tracking, document management, general marketing, and much more.
A QR code consists of black modules (square dots) arranged in a square grid
on a white background, which can be read by an imaging device (such as a
camera) and processed using Reed-Solomon error correction until the image
can be appropriately interpreted; data is then extracted from patterns
present in both horizontal and vertical components of the image.

code now that I’ve made one?
QR Codes are hyperlinks most commonly used to connect individuals
reading print media to (URL) websites or multi-media digital content
and may consist of embedded information including:
- Product details
- Contact information
- Promotional offers or loyalty programs
- Event details
- Twitter, Facebook, MySpace IDs
- A link to your website or YouTube video
- Invitations
- Embedded phone numbers which the phone can dial
- Love letters or text messages
