Is any of this proprietary? Camera, blacklights, and zooming are nothing new. What would keep PSA or SGC from adding this to their service for half your price (and if they do, I want a cut!! It was my idea to add it!!
). I would say that people trust these well established companies far more than your new start up.
How about this scenario. Buy one of your wonderfully secure PSA 9 cards. Get it home, get rid of sticker, crack the slab, add my not so wonderful PSA 7 and resell without your little sticker. I do not care how secure you think it is, without that little sticker and number on the slab, it means nothing. The only thing that would happen is my buyer would then submit it to you and cry foul. But by then I am long gone...(by the way...people know me here and know I would never do this but this is not something way out of bounds)...
One more thing...your Comparative Arbitration idea is misguided...you are essentially charging people a small fee to see if you made a mistake or it was tampered with. If you services are so great...why would you even need this and for a fee no less.
So again...I say...
Really?
