Each Revealer Zero comes as a set of identical cards and a demo pair in a gift quality box.
The cards contain encoded noise that you can use to encrypt your secrets (see how-to).
Design and content of the demo pair may vary – the words will not form a valid seed to avoid anyone mistakingly using it. For demonstration only
The software necessary to encrypt your seeds is available as a plugin in the Electrum Desktop Bitcoin Wallet since version 3.2.
Be sure to download Electrum from the official website (https://electrum.org) or from the official repository (https://github.com/spesmilo/electrum) and no other website.
Material: Transparent PVC cards thermo-printed in black.
Card size: 86mm x 54mm x 0.8 mm
