2020 1 oz British Gold Britannia Coin (BU, MintID, AES-128 Encrypted)

MintID certificate cards include an encrypted NFC microchip. The microchip is encrypted with AES-128 bit protocols and is tamper-evident, meaning it will “die” if attempts to tamper with the card and chip are made. This results in a “tampered” or “invalid” reading when the card is scanned by your smartphone using the MintID app. Your smartphone must be running iOS 13.0 or later or Android 4.2 or later.

All of the 2020 1 oz British Gold Britannia Coins in this product listing come with the MintID certificate card. The blue card contains an individual capsule space to hold one 2020 British Gold Britannia coin. Each of these coins is available in Brilliant Uncirculated condition and can be instantly authenticated with the MintID app.

The MintID app can be downloaded to any iOS or Android device. To authenticate your 2020 1 oz British Gold Britannia Coin, simply launch the MintID app on your device and enable NFC in your device settings. All you have to do is navigate to the scan section of the app and tap the certificate card to the reverse of your smartphone. The app will then pull up the individual profile of the coin inside of that card.
