Every service interaction starts with the same clunky ritual: hunt for a confirmation email, read out a name at a counter, hand over a physical ID. It's friction that erodes trust, slows queues, and introduces risk for both sides.
The culprit isn't the people — it's the architecture. Static identity is disconnected from the services attached to it. ProntoIn fixes the architecture.
Three steps. Zero friction. Cryptographic certainty.
Book a table, purchase a gym membership, or register for an event. The credential is cryptographically linked to your ProntoID — no app download required.
Present your ProntoID QR code at the door. In under two seconds, the system confirms both your identity and your service simultaneously. No staff intervention needed.
Using Zero-Knowledge Proofs, the business receives only the attributes it needs: "Table for 4 — Verified." Your date of birth, address, and full identity remain completely private.
From the local bistro to global enterprise — two paths, one standard of security.
Get up and running in minutes with zero coding required. Turn any tablet or smartphone into a ProntoID scanner the moment you sign up.
Deep, invisible integration into your existing tech stack. ProntoIn becomes the identity layer your systems already trust.
// Verify a ProntoIn scan const result = await prontoid.verifyServiceToken({ qr_token: "pid_svc_a7f3c1e8b2d4...", service_id: "res_table_12_2000", attributes: [ "booking_confirmed", "guest_count" ] }); // Response { "verified": true, "booking_confirmed": true, "guest_count": 4, "scan_latency_ms": 380 }
Most businesses are breached because they hold too much customer information. ProntoIn flips the model: you verify the attribute, not store the data.
"Our front-of-house team went from checking confirmation emails to greeting guests by name in the same motion. Check-in queues simply disappeared."
"We run 12 venues. Having one identity layer across all of them — with zero data liability on our side — was exactly what our legal team had been asking for."
"The ZKP disclosure was the deal-maker for us. We verify age and membership status without ever touching personal data. Regulators love it."
