What should I look for when choosing an ID document scanning vendor?

A handful of concrete factors are worth evaluating carefully rather than relying solely on marketing claims or headline accuracy figures, since the practical differences between vendors often show up in the details rather than the top-line numbers.

Document coverage relevant to your actual customer base matters more than a vendor's total published template count, since a vendor claiming coverage of thousands of document types isn't useful if it doesn't specifically include the countries and document types your actual users will present. Ask directly about coverage for your specific needs, and ideally test with representative sample documents rather than assuming broad general coverage translates to your particular use case.

Accuracy and validation depth is worth understanding beyond a single headline percentage. Does the vendor cross-validate data across MRZ, visual zone, and barcode sources, or rely on a single extraction method?

Does it include check-digit validation, and does it offer document liveness detection to catch screen-photo or photocopy fraud attempts?

Integration effort and documentation quality genuinely affect how quickly and smoothly your development team can get a working implementation running, so it's worth having a developer actually attempt a trial integration rather than relying purely on a sales conversation's description of ease of use.

Data privacy and security practices deserve direct questions: where is data processed and stored, what's the retention policy, does the vendor offer on-device processing, and what compliance certifications does it hold, particularly if you're operating under GDPR or similar regulations.

Pricing structure and how it scales with your actual expected volume matters for long-term budgeting, since per-scan pricing and subscription models produce very different cost trajectories depending on your growth pattern.

Ongoing support and how actively the vendor maintains and expands document coverage over time is worth asking about directly, since document coverage isn't a one-time achievement, and a vendor with a dedicated team tracking new document releases will serve you better over the long term than one treating coverage as static.

ScanDoc is happy to walk through each of these considerations directly, including document coverage for your specific needs, validation and fraud-detection depth, and a hands-on demo to evaluate real integration effort before you commit.
