Project Specs
FacePe Payment.
Face-authenticated payment experience focused on speed, trust, and accessibility at the point of sale.
Overview Brief
FacePe is a face-authenticated payment experience designed for the point of sale — built around sub-second authorisation, clear trust signals, and accessible fallbacks for users who can't or won't use card or phone.
Face-authenticated payment experience for point-of-sale retail.
What was broken
Card and PIN checkout is slow — queues build at peak. Need sub-3-second authentication customers actually trust with biometric data. Tension: speed vs. trust vs. accessibility, all at once.
How I worked it
4 decisions
- 01
Interviewed cashiers and shoppers — trust, not speed, was the #1 adoption blocker.
- 02
Designed explicit consent flow + live feedback states (scanning / matched / failed) so user always knows what the camera is doing.
- 03
Used motion cues to reduce perceived wait time during auth.
- 04
Built accessible fallback path for failed scans — no dead ends, always a way to complete payment.
What it shipped
TODO: real metric — auth time, match success rate, or pilot result. Placeholder qualitative: shipped clickable prototype validated in stakeholder review; consent pattern adopted as team standard.
Trust UX mattered more than raw speed UX. Next iteration: test under low-light store conditions and edge-case faces.
“How do you replace card-tap with a face scan without sacrificing the trust signals shoppers rely on at the till?”
The Objective
Deliver a confident, transparent payment flow that handles success, failure, and retry in under four seconds end-to-end — at any merchant, in any lighting.
Key Features
5 Core Verticals
Sub-second face authorisation with continuous visual feedback during the scan.
Trust scaffolding — encrypted, biometric-stored, never shared — surfaced at every step.
Accessible fallback (PIN, OTP, card-tap) reachable from every screen.
Receipt and transaction history built into the same flow, not buried in a menu.
Multi-merchant onboarding tuned for ten-second setup at a new till.
