To produce its stunning silver bars, MintID works directly with ISO:9001 minting facilities that produce silver bars using only LBMA/COMEX approved precious metals. Individual MintID products have a unique, encrypted NFC microchip applied directly to the surface of the item. In the case of these 5 oz MintID Silver Bars, that tamper-proof chip is present on the reverse field of the bar. All 5 oz MintID Silver Bars are available to you in brand-new condition. The bars in this weight are the second option introduced after the 10 oz silver bar. Like its larger counterpart, the 5 oz MintID Silver Bar is individually packaged inside of a sealed plastic sleeve. Each one of the silver bars from MintID is physical silver you can hold that has a secure, individual digital identity stored in the cloud and only accessible by you as the owner of the bar. The obverse side of 5 oz MintID Silver Bars includes a depiction of the mighty American bison. The bison is the largest land mammal in North America and consists of two subspecies: plains bison and wood bison. The plains bison can be found in both the United States and Canada, while the wood bison is largely confined to Canada in the modern era. Other markings on this face of the bar include the MintID name and logo, with the weight, purity, and metal content included. On the reverse face of the 5 oz MintID Silver Bar is an image of the MintID logo. This logo consists of the company name with a basic depiction of a smartphone. This design element repeats throughout the background field with the blue, scannable NFC microchip in the center of the bars design field. All MintID silver products can be instantly scanned using the MintID mobile app. Available for Android 4.2 or later and iOS 13.0 or later devices, you dont need a paying account and wont have to provide any sensitive information to scan and authenticate your MintID silver.
