I'm a bit disappointed in this article. Interviewing someone who bought fake IDs and a small scale seller from 1994 isn't that insightful. He should have tracked down a current seller and interviewed them.
Prices have dropped in the past 10 years which I assume means increased competition. It would be interesting to hear how that has affected the business. I'm also curious about the techniques they use. When I was selling IDs 13 years ago it was teslin, PVC card printers, and Alps printers. I assume the Alps printers are no longer used since they went out of production in 2003 or 2004.
A lot of IDs are still fairly easy to replicate. The hardest thing is a real hologram which most IDs don't have.
