Choosing a document verification partner is a significant decision. This page helps procurement and operations teams understand how TamperCheck compares to Onfido - on pricing, privacy posture, and what it actually takes to get started. Note that TamperCheck works on digital PDFs and scanned hard copies alike - including physical stamp verification and handwritten signature analysis, not just native digital files.

When to choose TamperCheck
- You already have capture and onboarding and only need a deep tamper + AI adjudication pass on the file bytes.
- You want managed AI inference, published $/document economics, and an ephemeral document story without buying a full IDV suite.
- You’re building internal or B2B tools where a lightweight verdict endpoint beats rolling out consumer-grade liveness flows.
When to choose Onfido
- You need regulated KYC out of the box: liveness, face match, watchlists, and vendor attestations for identity programs.
- Your product is consumer onboarding and you want mobile SDKs + hosted journeys, not only server-side PDF analysis.
- Procurement wants a named global IDV with broad country coverage and enterprise support SLAs.
Full identity suite vs. specialist document forensics
Onfido’s natural buyer is building identity verification as a capability: who is this person, does the selfie match the ID, is the session real? TamperCheck’s buyer is often asking a narrower technical question: is this PDF or image internally consistent, and what looks edited or AI-generated?
You might even use both: Onfido (or similar) for the identity journey, and TamperCheck when you want forensic depth and control on the exact file your risk team is arguing about. The differentiator is whether you’re purchasing platform identity or a focused tamper API.
TamperCheck vs Onfido: common questions
Is TamperCheck an alternative to Onfido?
For document authenticity, yes - and for identity verification, no. Onfido answers whether a person is who they claim to be. TamperCheck answers whether a document is what it claims to be, including the bank statements, payslips and certificates that never pass through an onboarding session at all.
Can I use Onfido and TamperCheck together?
Yes, and many teams do. Onfido (or any IDV vendor) handles the identity journey at signup; TamperCheck handles every document that arrives afterwards - income proof, address proof, invoices, credentials - with per-field tamper analysis and AI-generation detection. They cover different halves of the trust chain.
Which one detects AI-generated documents?
TamperCheck runs a dedicated AI-generation and deepfake pass on every upload and localises the finding to the individual field. An IDV platform's document checks are built around the capture session and identity documents; documents submitted by email or through your own forms are outside that flow entirely.
