IDfier vs Optical flow Analysis

Tired of texting strangers a photo of your passport? Same. IDfier lets you verify your ID once, then share a verified version of yourself with anyone who needs it, without handing over the document itself. How it works: 1. Scan your passport, national ID, or driver's license. Tap your phone to the chip if it has NFC. Take a quick selfie so we know it's you. 2. Build the things you want to share. An age check. Just your name. Full ID. A driver's license. Whatever the situation calls for. 3. Send it. QR code in person, link or short code online. They see verified data, not a screenshot. That's the whole thing. What people use it for: • Meeting someone from a marketplace or dating app and wanting to know they're real • Proving they're over 18 without showing their personal number and birthday • Renting a place, signing for a delivery, picking up a package • Onboarding to platforms that ask for ID without uploading documents to who-knows-where • Creators and freelancers who want a public profile that says "I'm a real person", not just another link-in-bio Three trust levels: Bronze covers the document scan and face liveness check. Silver is for BankID users in Sweden. Gold adds a face liveness check to Bronze. The more you verify, the more weight your shares carry. Login with IDfier: Some sites and apps let you sign in by scanning a QR code with IDfier. You see exactly which fields they're asking for and approve each one. No more uploading ID photos to random websites. Pricing: The first 10 exchanges are free. After that you top up with credits or subscribe for unlimited use. We don't sell your data, that would defeat the point. A few things worth saying: • Your documents stay on your device. We don't keep copies. • The app locks behind Face ID or Touch ID. • Sweden: BankID works as a shortcut for the initial verification. • Everywhere else: we read documents from over 200 countries. If something's broken or weird, the feedback button in your profile goes straight to us. We are all ears. — The IDfier team
