• Cards encoded with this system would have a thin stripe of nanoparticles added to the back in place of the standard magnetic strip. When a card is issued, a laser would project a few photons of light at the nanoparticles
  • Because of the quantum nature of photons, each one can essentially be in more than one place and create a complex and unique pattern in the strip
  • Reading one of these cards would require special hardware similar to the laser used to create the pattern in the first place. Terminals would be able to fire a bundle of photons into the strip and reach the resulting unique response
