QR Codes

Nope, they're not modern art of ink blotches. These are QR Codes or "quick response codes". These are like barcodes and are readable via a QR Code scanner or smartphone with the appropriate software installed. Download a barcode scanner or qr code scanner application on to your phone to use these.

In Reeko's Mad Scientist Lab, QR Codes are used to provide secret messages (e.g. where to find the hidden pots of gold), science tips, and in some cases, just to mess with your head.

QR Code History

QR Codes were created in Japan in 1994 and have been quite popular there for some time. QR codes were originally developed to track parts in a factory but have since spread to the mobile web where they are used to specify website URLs and do a bunch of other cool stuff (like automatically dial your phone).
