    Encrypted on your phone

    Before anything reaches the card.

    Hold it to your phone and the vault is saved.

Who can open it

A found card is not enough

FAQ

Before you buy

Someone finds a card I lost.

They have an unlabelled card containing encrypted data. There is nothing on it that identifies you or the vault.

I lose my phone.

Install MI8OS on another compatible phone, tap any card and enter the vault password to restore access.

I forget my vault password.

The vault cannot be reset or recovered. There is no reset option, recovery code or hidden way around the password.

MI8OS as a company disappears.

Your cards do not depend on an account or MI8OS server to hold their data.

Does the card need charging?

No. It has no battery and is powered by your phone during a tap.

Which phones work?

An iPhone or Android phone with the MI8OS app and a working contactless reader.
