In recent years, the precious metals market has seen an increasingly worrying number of fake kilobars (in which other metals like tungsten are present or which do not contain gold at all) as well as counterfeit kilobars (made of high purity gold, but with forged serial numbers and hallmarks imitating reputable manufacturer).
To ensure the integrity of the bullion market, SICPA, the leading Swiss provider of global security solutions for currencies, and Metalor Technologies have jointly developed a technology-based security feature called BullionProtect®. A special high-security ink is applied directly to the surface of the bullion, adding negligible weight (<20 mg). Its security is built on proven technologies with high anti-counterfeit robustness that have been used in specialized markets, such as passports, for more than a decade.
