Strict protocols and procedures are in place to ensure that banks and other stakeholders can source trustworthy gold from refineries with stipulated purity and controlled origin. Gold bullion carries company hallmarks as a signature of quality. Faked or counterfeit gold bars may carry reproductions of hallmarks, damaging the reputation renowned manufacturers as well as compromising the integrity of the international gold market.
Swiss company SICPA, the leading provider of global security solutions for currencies, has jointly developed a technology-based security feature, BullionProtect®, with Metalor Technologies. In line with LBMA guidance, the solution enables all actors within the supply chain to authenticate precious metal products.
The security seal has inherent properties that can be unequivocally and instantly identified and verified through different authentication means.
The visual verification can be performed with a credit-card size validator that is easy-to-use. It takes only a few seconds to validate the security seal.
When viewed with the validator, this design label turns green under the left filter and the patterns brighten under the right filter.
The visual authentication can also be performed with a specific flashlight. This handheld device is well suited when lighting conditions are poor and for large volume verification. It takes only one minute to validate more than 100 security seals.
The blinking flashlight reveals, through two alternating beams, the same colour and pattern changes as with the credit-card size validator.
