<p>[QUOTE=&quot;calcol, post: 4615142, member: 77639&quot;]As I said in a follow-up post, the PCGS server remembers the random number it received with the ID number.&nbsp; If it sees it again, it will know that the newest attempt is fraudulent.</p><p><br /></p><p>BTW, the method I described is just one of many that will work.&nbsp; Another is for PCGS to download a few million different codes into the chip that are unique to that slab.&nbsp; Each code will be used by the chip only once.&nbsp; So if a counterfeiter captures a code from a genuine slab and puts it in a fake, it will do no good.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
