Updated: 2026-08-20 Query: how to sign with a Lithuanian ID card using NFC on a phone

What happens when you sign

Contactless QES uses the physical national ID card together with an NFC phone. You open the Tvarka app, confirm the signing action, and hold your card against the phone.

Access to a legal entity in Tvarka is granted by the Manager. An accountant, an assistant or another representative can be invited to work on behalf of the company, and each of them signs with their own ID card.

When it is the convenient route

The NFC route suits you when you would rather not buy a USB reader, or when you are signing away from your own desk. It is also a good route for companies that want cheaper qualified signing and hold newer ID cards.

If contactless signing with a phone and a card does not suit the moment, Tvarka offers the alternatives: Smart-ID, Mobile-ID, LT ID or USB/eID.

Frequently asked questions

Is an NFC signature qualified?

Yes, when signing uses the qualified certificate on the ID card and the Tvarka qualified signing flow.

Does the private key ever leave the card?

No. The signing logic relies on the secure means inside the card; Tvarka receives only the signing result and the audit information.

Does the Manager have to perform every signature personally?

No. The Manager decides who gets access. An invited user works within the rights granted and signs with their own means.
