Choosing a document verification partner is a significant decision. These pages help procurement and operations teams understand how TamperCheck compares to the tools they're evaluating — 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.
TamperCheck vs Persona: full-stack identity orchestration vs. forensic document API
Persona is a massive identity orchestration platform (IDV, KYC, KYB, manual review workflows) with a drag-and-drop builder. TamperCheck is a single-purpose forensic API for document tampering. Use Persona to build your entire onboarding flow; use TamperCheck when you just need to know if a specific PDF or image is fake.
Transparent pricing: TamperCheck publishes $0.50 per document after your $5 credits — pay-as-you-go, no seat fees, no opaque tiers. Full pricing →

When to choose TamperCheck
- You already have an onboarding flow and just need to add forensic checks to file uploads (like pay stubs or invoices) that standard IDV doesn't cover.
- You want BYOK and transparent $/doc pricing without migrating to a new identity platform.
- You need zero data retention for sensitive document processing.
When to choose Persona
- You need to build an end-to-end KYC/KYB onboarding flow from scratch, including UI, liveness checks, and database verifications.
- You want a manual review dashboard where your agents can inspect flagged users and documents.
The identity platform vs. the forensic microservice
Persona is an incredible tool for orchestrating identity. If you need to ask a user for their ID, take a selfie, check a government database, and route them to a human reviewer if they fail, Persona is the gold standard. TamperCheck does none of that.
TamperCheck is a microservice for document forensics. If you have a backend process that receives a PDF or image and you need to know if it was manipulated in Photoshop or generated by AI, TamperCheck gives you a definitive answer in 3 seconds. Many companies use Persona for user onboarding and TamperCheck for ongoing document submissions.
