BStrauss3 Pillar of the Community United States 4593 Posts	Posted 04/13/2022 8:47 pm I posted on this in one of the many threads, instead of digging, repost When the tag is read, it generates an ordinary https page read. The request includes the cert# and a piece of time-based data. The request can be resubmitted for up to 3 or 5 minutes, after which you are told it's invalid and you need to scan the tag again. Even if you buy the same tags (and they are not PCGS proprietary), you can't generate the same request from just the cert#. I doubt it would take nation-state resources to crack the keys and nonces, but PCGS could make it far more difficult to usefully crack by generating new keys and nonces every few thousand slabs. There are plenty of processes where the morning startup includes re-keying secure processes. -----Burton 50+ year / Life / Emeritus ANA member (joined 12/1/1973) Life member: Numismatics International, CONECA Member: TNA, FtWCC, NETCC, EveryCountry (online) coin club Owned by three cats and a wife of 40+ years (joined 1983) Author: 3rd Edition of the Sample Slabs book, https://www.sampleslabs.info/ Report this Post to the Staff

I would rather not have my valuable coins traced to my name using an outside program. It is vital for every collector to develop his own skill of Counterfeit Detection, not just trusting a TPG's opinion and a computer program entirely.
