The Global eID Acceptance network
Hopae is the eID orchestration platform powering the shift from document verification to digital identity. Through a single API, Hopae gives identity verification providers and regulated businesses instant access to government eIDs and digital wallets worldwide — turning what used to take months of legal, technical, and compliance work into an integration that goes live in days. As regulations like eIDAS 2.0 accelerate the global rollout of digital credentials, Hopae has become the leading platform for global eID and wallet coverage, trusted by top identity verification providers to onboard customers faster and stay ahead of compliance. Our team has been at the frontier of this industry for years — including building the digital identity infrastructure behind South Korea's COVID-19 vaccination credentials, used by 43 million people. We're building the trust infrastructure for a world where every credential — from your eID to your boarding pass — moves seamlessly and securely. This is the new standard for digital identity.
