<p>[QUOTE=&quot;TypeCoin971793, post: 4151408, member: 78244&quot;]You raise an extremely important point that I did not consider; so important that I may ask [USER=112]@GDJMSP[/USER] to put add it to my list of mitigation techniques in my original post.</p><p><br /></p><p>When the counterfeiters are creating their fake labels from a database, they use canned barcodes that do not match those of the genuine slabs. If you are correct in that the apps read the barcodes, then that will render the vast majority of fake slabs useless to anyone who has the coin in hand and a smartphone with a connection.</p><p><br /></p><p>However, the fraudsters can print out pictures of the labels from Heritage or NGC’s website. The prints would typically be much lower quality than that of genuine holders, but the barcodes would be the same.</p><p><br /></p><p>As a result, I am going to ask all of you to perform an experiment for me. See if the apps can verify on-screen images of genuine slabs. Then find three images (Heritage picture of NGC slab, Heritage picture of PCGS slab, and NGC picture of NGC slab) and print them out, making sure that they are roughly the correct size. Then see if you are still successful in getting the “slab” verified. Post your results. If your printouts are successful, DO NOT share what printer you used.[/QUOTE]</p><p><br /></p>
