OBI (WIPO) invention patent 20210100177, "Gold Bullion Origination and Verification System with Unique Identification by embedding Traceable Ingredients"

The golden coin and bullion market today suffers from unlimited falsifying attempts. Counterfeiter from ancient times find their way to illegal profit. Today to verify gold pureness analytical machines are in use. The main issue is that they cannot identify every single bullion for anti-money laundry law enforcement. Our solution is to insert inside the golden bullion, between casting and minting a number of distinguish ingredients (9). These traceability elements irrevocable and unique identify every golden bullion or coin. After minting (5) the secure identification recognition system (6) uses sensors like Electrical Conductivity sensor(33), heat transfer sensor(35), full Radio-Frequency system(37), X Ray fingerprint(39) and acoustic sensors (41) to give a unique certified Identification number (6) with associated detailed anti-forgery data. The bullion with a certified ID is definitely gold, unlike any other non-certified “possibly gold” bullion.
