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 Microblink: server-side tamper verdicts vs. capture-first identity SDKs
TamperCheck is built around analyzing documents you already have—server-side forensics + AI with BYOK. Microblink (BlinkID, etc.) is famous for mobile capture, extraction, and on-device identity experiences—meeting users where they scan IDs, with fraud features adjacent to that flow.
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
- Documents arrive server-side (email, back-office, partner uploads) and you need forensic analysis without a camera SDK.
- You want BYOK and $/doc pricing for batch or API workloads.
When to choose Microblink
- You’re optimizing mobile onboarding UX with scanning, NFC, and on-device performance.
- You need BlinkID-class capture as part of a consumer identity journey.
Backend forensics vs. client capture excellence
Microblink wins when the problem starts with getting a clean image from a user’s phone. TamperCheck wins when the problem starts with a file already in your system and you need explainable tamper signals for analysts.
Many teams use both layers: great capture up front, and a second-line forensic API when a document still looks wrong—or when the file never went through your app camera at all.
