Collectable coin grading service combats counterfeiting with NFC

Collectors, investors and dealers in rare coins, banknotes, medals and tokens can now verify the authenticity of items certified by the US-based Professional Coin Grading Service by tapping an NFC chip embedded in PCGS holders with their smartphone.

PCGS has begun inserting NFC chips developed by HID Global in its coin and banknote holders to combat counterfeiting, to provide information about the items they contain, and to confirm that they are genuine and have PCGS Cert Verification.
