Choosing a document verification partner is a significant decision. This page helps procurement and operations teams understand how TamperCheck compares to Microblink - 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
- Documents arrive server-side - email, back-office, partner uploads - and you need forensic analysis without a camera SDK.
- You want managed AI inference and per-doc pricing for batch or API workloads.
- Digital signatures are verified, not just displayed. When a document carries one, we resolve the certificate itself: who issued it, whether that issuer is on a trusted list, and whether the chain is complete.
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's job ends the moment a clean image leaves the user's phone. TamperCheck's begins with the file already in your system - including every document that never passed through anyone's camera - and returns field-level, explainable tamper signals an analyst can act on.
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.
TamperCheck vs Microblink: common questions
Is Microblink a document fraud detection tool?
Microblink's core strength is capture - getting a clean, well-framed image from a user's phone, with on-device scanning and NFC reading. Forensic analysis of an arbitrary uploaded PDF or emailed scan, and detection of documents generated by AI, is a different problem. That's what TamperCheck is built for.
Can I use Microblink for capture and TamperCheck for verification?
Yes - it's a natural pairing. Capture the document cleanly at the front end, then pass the resulting file to TamperCheck for 200+ forensic layers, per-field tamper localisation and AI-generation detection. Neither product duplicates the other.
Does TamperCheck work on phone photos and scans?
Yes. Camera captures, flatbed scans and native PDFs are all first-class inputs, including physical stamp verification and handwritten signature analysis. Documents that arrive by email or through your own web forms - never touching a capture SDK - are the common case.
