<p>[QUOTE=&quot;calcol, post: 17654995, member: 77639&quot;]Pretty neat panzerman.&nbsp; I do something similar with my ancient coins, which are still in flips.</p><p><br /></p><p>When chipping slabs for more than security reasons begins, it will be cheap to include some user memory.&nbsp;&nbsp; Might be an extra cost item.&nbsp; Bluetooth is one communication interface, but there are others.&nbsp; Anyway, with some user memory, the owner could transmit additional information about the coin to the chip memory.&nbsp; The additional information could be description, variety, references, provenance, where and when bought, price, inventory number, etc.&nbsp; Only a phone would be needed to change it or read it.&nbsp; A lot more info can be put in a chip than on a label, and it can be encrypted if desired.&nbsp; And editing it will be a lot easier and quicker.</p><p><br /></p><p>At some point, it might be financially feasible to have a small scrolling screen as the slab label.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
