Why a chip card

A key that can be copied is no key.

Most wallets store your private key directly on your smartphone. This is convenient — and precisely the weakness: whatever data is present on the smartphone can be copied. Anyone who has a copy can impersonate you without anyone noticing.

The DI Card separates both. The smartphone displays your credentials, while the card proves that they belong to you. The key is generated within the security chip and technically cannot leave it — the same principle that has protected your bank card for over 25 years.

How to use the card

Unpack, pair, done

No computer setup, no card reader, no extra software other than the app.
Step 1

Download app

Install the IDealWALLET app. Free, no online account required, no email registration.

Step 2

Pause DI Card

The app detects the chip card via NFC and links it to your wallet. From now on, your key is on the card — and only there.

Step 3

Securely use evidence

Please confirm the receipt or presentation of evidence briefly with your ID Card. It is like your signature in the analog world – and no one else can do it for you.

What the ID card does for you

Small and secure as a bank card.

There are incredibly many advantages to not storing a digital identity in a replicable environment. But there are benefits beyond just security.

Not copyable

The key is generated inside the chip and never leaves it. There is nothing that could be copied.

Independent of the mobile phone

New device, lost device, hacked device — your identity remains on the card in your pocket.

Without battery, without mains power

The card draws its power from the smartphone when tapped. No charging, no internet, no wear and tear.

Independent

No key in the chip from an American or Asian device manufacturer. Developed in Dresden.

For Organizations

Do you need more than one DI Card?

For employee ID cards, access rights, or customer identification, we supply the DI Card in large quantities - special editions are also possible!

Are you already using other smart cards as employee IDs or Mifare access chips? We can also offer these cards as multimodal smart cards, where all security systems can be operated with a single card. Contact us!

In Brief

Questions about the DI Card

We are currently developing support for software-based cryptography as well. While this is less secure, the official wallet of the Federal Republic of Germany will issue credentials at this lower level of security.

Until we complete this implementation, you can only use the app with the DI Card. The advantage: With the card, your key is not stored on the smartphone, but in a security chip — for anyone who does not want to entrust their identity to a device.

Nothing that would compromise your identity. The key is on the card. Install the app on the new device, pair the card — and you are back in business and can have your credentials/authorizations reissued.

Without your smartphone and your PIN, a person who finds the card cannot do anything with it. You are using a successor card, which, just like in real life, you have designated as the heir to your previous DI Card. That is precisely why the starter set will always contain 2 DI Cards, so that you always remain able to act in the event that one DI Card is lost.

With any smartphone that supports NFC - which means almost all current devices. Does contactless payment work for you? Then the DI Card will also work.

Yes. For example, one for private use and one for work — each with its own keys and credentials.

We ship from Dresden within two business days. Within Germany, it will generally arrive within two days.

We send the DI cards via DHL with tracking. The cost is €6.90 per package.
