From the story:
"A chip smaller than the head of a pin is placed onto a DVD along with a thin coating that blocks a DVD player from reading critical information on the disc. At the register, the chip is activated and sends an electrical pulse through the coating, turning it clear and making the disc playable."
This appears to be a decent use of security technology, but what is the potential of this being the new DIVX?"
