MintID protects precious metals with NFC chips

MintID has introduced a series of gold and silver bars and coins that use tamper-proof NFC security chips to provide bullion investors with assurance that they are buying a genuine product. Each of the company’s products includes a custom-designed NFC chip that has a unique encrypted and tamper-proof digital certificate. Physical precious metal investing has many advantages. Unfortunately, until now investors have been plagued with the uncertainty of whether or not the products they own are actually genuine.
