# Tessera — EU Age Gate for Shopify
# https://tessra.eu

> EU Age Gate is a Shopify app for privacy-preserving age verification.
> Customers prove they are 18+ using their EU Digital Identity Wallet
> (EUDIW): the wallet presents an eu.europa.ec.av.1 mDoc credential via
> OpenID4VP and shares only a single boolean (age_over_18). No ID uploads,
> no selfies, no personal data collected or stored. eIDAS 2.0 compliant.
