About CIDX

One credential layer. Your whole life.

CIDX turns a single verification into a portable, cryptographically-signed digital pass — accepted by any institution, across finance and health, anywhere in the EU.

Why we exist

The information already exists.

The cost of asking people to re-prove their identity over and over adds up to a staggering waste — roughly €50 billion a year in Europe, paid by everyone. The real cost is the time patients spend repeating their history, the customers who give up halfway through, and the doctors who order tests they know have already been done.

CIDX is the credential layer that connects your verified identity to every institution that needs to trust it. One check. Used everywhere. We are based in Luxembourg and built for the EU — GDPR-compliant, with your data stored securely in Europe.

Verified once

You have already proved who you are to a government, a bank, a doctor. We make that proof portable instead of asking for it again.

You stay in control

Nobody can access your pass without permission. You tap to share, and you decide exactly what each institution sees.

Built on the EU standard

Credentials live in the EUDI Wallet and are cryptographically signed — legally recognised across every EU member state.

Cannot be forged

Every institution that receives a CIDX pass can verify instantly that it is real, issued by a trusted source, and unaltered.
