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 $/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.
