Identity verification and KYC
Tessio vs iDenfy
iDenfy is an EU based identity verification and KYC provider that recently added facial age estimation. Tessio is a wallet native age verification API that stores no documents or dates of birth and proves someone is over 18 with the EU age verification app (the EU Digital Identity Wallet follows once our access certificate is issued).
iDenfy does document OCR and selfie matching across thousands of document types, with AML tools and, more recently, a facial age estimation option and a standalone deployment. Based in Lithuania, it is a cost conscious EU option for teams that want IDV and KYC together.
Tessio is narrower. It confirms one claim, over 18, from a wallet credential and returns a signed yes or no with no document or date of birth kept. There's no document scan and no selfie. If you only need an age check, you avoid collecting the identity data that a full IDV flow requires.
Tessio and iDenfy, side by side
| Tessio | iDenfy | |
|---|---|---|
| Core approach | OpenID4VP presentations from the EU age verification app (EU Digital Identity Wallet to follow) | Document OCR and selfie match, with a newer facial age estimation option |
| What you get back | A signed over 18 yes or no | An identity verification or age estimation result |
| Personal data stored | The yes or no and your reference. No date of birth, no document image, no selfie | Processes ID documents and biometric data |
| EU Digital Identity Wallet | The EU age verification app works today. The EU Digital Identity Wallet follows once our access certificate is issued. | Baltic national eID (Mobile-ID) integrations. No EUDI native wallet verifier we could find, so verify |
| Self hosting | Yes. Open source .NET core under Apache-2.0 | Offers a standalone deployment option, though not an open source self host like ours |
| Full KYC and AML | No. Age assurance only | Yes |
| Built on | Open source ASP.NET Core (OpenID4VP, SD-JWT VC, mdoc) | Proprietary |
| Primary market | EU age assurance for regulated platforms | Affordable EU identity verification and KYC |

When to choose iDenfy over us
If you want an affordable EU platform that does full document verification and KYC, plus age estimation as one option among many, iDenfy covers more ground than Tessio does. When you need identity proofing and not just an age gate, a full IDV provider is the right call.
When teams pick Tessio
Pick Tessio when age is the requirement and you would rather check a wallet credential than scan documents. You get a signed over 18 boolean with no document or date of birth stored, and the .NET core is open source and self hostable.
Frequently asked
Is Tessio an iDenfy alternative?
For age verification, yes. Tessio proves someone is over 18 with the EU age verification app without collecting a document or selfie. iDenfy does full IDV and KYC, so it does more than Tessio when you need to verify identity rather than just age.
Does iDenfy support the EU Digital Identity Wallet?
iDenfy integrates Baltic national eID such as Mobile-ID, but we could not find a native EUDI Wallet verifier. If native EUDI support matters to you, confirm the current state with iDenfy directly.
Can I use both?
Yes. iDenfy can handle full identity verification where you need it, while Tessio handles the age gate where a yes or no is enough and you want to store no documents or dates of birth.
