After several years of developments and successful field tests, we are proud to announce the availability of our system for the authentication of precious metals. This technology enables to automatically check if a gold ingot or coin is genuine. It works with our dedicated iPhone app and does not require an extra lens or other external device. Moreover, no modification of the ingot or coin is required, and the technology is compliant with both minted and cast products. We also developed a specific server web application based on our Brand Monitoring System which enables our customers to manage protected ingots and to monitor all authentications performed by end users. The smartphone app is easy to use and available to the general public. Presently, thousands of authentications have been successfully performed all over the world. We anticipate that coin and bullion manufacturers will show great interest in this new solution.
