Proof your buyer approved the order — with one biometric scan. No app. No passwords. No friction.
Every dispute demands evidence — but most social sellers and small merchants are left pulling proof from everywhere at once.
Screenshots. DMs. Tracking pages. Emails. Each one tells part of the story, but not the whole thing.
Lost sales
Revenue reversed even when you did everything right.
Lost hours
Time spent scrambling for evidence instead of selling.
Account instability
Rising dispute rates can damage your standing with platforms.
Onfinga sits quietly around your existing checkout and payment links. Before the buyer pays, they complete a quick biometric scan on their own device. We record that approval in a tamper-resistant way you can rely on later.
Biometric buyer approval
One scan on the buyer’s own device confirms intent before payment.
Time-stamped proof of intent
Clear records of when the buyer authorized the order.
Proof aligned with what card issuers, banks, and processors look for
Evidence structured the same way dispute reviewers evaluate cases.
For the buyer, it’s just one quick verification and then payment like normal. For you, it’s a complete trail of proof.

Buyer scans their fingerprint or face
They’re automatically redirected to your payment provider
You keep using PayPal, Venmo, Cash App, or any other payment service. Onfinga simply adds the proof.
Simple, usage-based pricing that fits social sellers and growing merchants.
Onfinga stores only what matters — proof, not card numbers or identities. We don’t replace your payment provider and we don’t try to be your data warehouse. Each approval record is signed and tamper-resistant, so you can reference it when you need it without holding unnecessary sensitive data.
Onfinga was created for one purpose: to give online sellers clear, reliable proof of what really happened in a transaction. No noise. No heavy dashboards. Just a small verification step that protects the sale without adding friction. We focus on one thing — the proof you need, when you need it.
