<p>[QUOTE=&quot;Conder101, post: 1924755, member: 66&quot;]Until the counterfeiters start attending auctions with a reader equipped to read and record the signals from the RFID chips.&nbsp; Go through lot viewing recording the chips and then make fake slabs with chips programmed to broadcast the same signals.&nbsp; The chip reader apps then show them as real.</p><p><br /></p><p>Doug</p><p>Where does the buyer get this second number that isn&#039;t on the slab? From the seller?&nbsp; Does the seller now have to keep records of all his slabs and the &quot;secret number for each of them?&nbsp; What happens if someone loses this secret number?&nbsp; The slab can&#039;t be sold until it is sent back to the TPG for confirmation and a new secret number issued (with a fee for the service of course)?&nbsp; And of course having to look up the secret number everytime someone wants to look at a coin is going to get annoying, so we&#039;ll just make up stickers and put the secret numbers on the slabs to save time.&nbsp; there goes that security feature.&nbsp; not to mention all this scanning, getting numbers making phone calls and waiting to be called back is going to get extremely annoying very quickly.&nbsp; So people start buying without all the calling and guess what the secret numbers start getting lost even faster.&nbsp; Sorry Doug I just don&#039;t think it is practical.[/QUOTE]</p><p><br /></p>
