The card for your secrets

You carry cards for money and travel. Why not one for your secrets?

Your wallet already holds a bank card, a transit card and a loyalty card. MI8OS adds one that holds your most important text, encrypted.

Every card in your wallet has a job

One pays, one opens the office door, one collects points. None of them looks after the secrets you can’t afford to lose.

A MI8OS Card carries an encrypted copy of your vault. It looks like any other card and gives nothing away on its own.
