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.
