This is a new type of barcode called an "EM Code".
The information is transmitted in a manner similar to Morse Code using light instead of electrons hence the EM stands for electromagnetic.
Most modern Android and ioS smartphones will be able to decode an EM Code using the built-in camera and the JAPER App.
We will shortly publish the EM Code EBNF.
This EM Code contains 64 bits @ 20 bits/second.
EM Codes can be very small and they draw the eye.
The human attention reflex can be activated by the careful use of EM Codes as tiny visual stimuli. 
We do not recommend using EM Codes in large sizes due to the nature of human photosensitivity in approximately 3% of the population.
It could be argued that an EM Code is the smallest surface area barcode possible, 1 blinking pixel is all it takes.
