Identity verification and KYC
Tessio vs Veriff
Veriff is a mature global KYC platform built on document and biometric checks. Tessio is a much narrower tool 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). If all you need is an age gate, that difference is the whole story.
Veriff verifies identities worldwide. A user photographs an ID document and their face, Veriff matches them against thousands of document types across almost every country, adds liveness and fraud signals and returns a full identity verification result. It is a strong fit for onboarding where you need to know who someone is.
Tessio isn't trying to do that. It answers one question, is this person over 18, using a credential from the EU age verification app. There is no document capture and no biometric processing, and we keep no documents or dates of birth. If you only need an age check, you don't have to take on the data that full KYC brings with it.

When to choose Veriff over us
If you need to verify identity, not just age, Veriff is the stronger tool. Veriff is built for full KYC, AML screening, document capture and fraud monitoring across almost every country. Tessio does none of that. When your compliance obligation is know your customer rather than confirm the customer is an adult, go with a platform like Veriff.
When teams pick Tessio
Pick Tessio when the requirement is age rather than identity and you want to hold no documents or dates of birth. You get a signed over 18 boolean, so there is no document image or biometric template to secure or breach. If data cannot leave your environment, you can self host the .NET core.
Frequently asked
Is Tessio a Veriff alternative?
For age checks, yes. If you only need to confirm someone is over 18, Tessio does it without collecting a document or a selfie. If you need full KYC and identity proofing, Veriff does far more than Tessio does, so it depends on the obligation you're meeting.
Does Veriff support the EU Digital Identity Wallet?
Veriff lists the EU Digital Identity Wallet among accepted document types, so it can take a wallet credential as an input to its identity flow. Tessio returns only an age result, and its live checks use the EU age verification app. The EU Digital Identity Wallet follows once our access certificate is issued.
Can I use both?
Yes. Use Veriff for full identity onboarding where you need it. Use Tessio for the age gate where you only need a yes or no and would rather not store documents or dates of birth.
