REGISTRATION TUTORIAL: https://www.youtube.com/watch?v=EvR0j9ulNnA Please email us at support@bluink.ca if you have questions or need assistance. INTRODUCTION eID-Me is a secure digital identity app. eID-Me digitizes and securely stores government-issued identity and self-managed identity information on your iPhone. eID-Me makes online identity verification quicker, easier, and more secure by eliminating passwords and strengthening privacy. eID-Me cannot currently be used as a substitute for legal identification. Our goal is to improve access to services that require verified identity, including government, financial, health care, and more. If you want to help speed up eID-Me integrations, spread the word. Share eID-Me content on social media. Show eID-Me to friends. Learn more at: eid-me.com/share. HOW IT WORKS During registration, use your iPhone to prove your identity by taking a selfie with liveness check, and scanning your government-issued photo identity documents (e.g., driver’s licence, passport). Your iPhone is then issued a unique eID-Me digital identity, which includes a digital certificate with identity claims (verified pieces of information about you). You can then use your eID-Me digital identity to easily access services and securely share identity information in identity transactions both online and offline (in person). PRIVACY AND SECURITY Your identity information is always in your possession on your iPhone. It is never hosted by a centralized service or third-party provider or stored in the cloud. Once your identity information is verified, a secure certificate is installed on your iPhone. That information is not accessible to anyone but you, until you choose to share it in a transaction. eID-Me’s digital wallet is protected on the iPhone with strong encryption, leveraging its hardware security mechanisms, and is bound to your authentication method (e.g., Face ID, Touch ID, PIN). BENEFITS AND FEATURES • Secure digital ID on your iPhone. • Secure digital wallet on your iPhone containing your identity with verified ID information. • No cloud storage of your identity information. • Strong encryption and certificate-based authentication. • eID-Me identity is bound to your iPhone’s authentication method (e.g., Face ID, Touch ID, PIN). • Strong privacy protection with complete control over your identity and information.
