Kairos Identity Verification vs Microblink BlinkID

Kairos Identity Verification combines document scanning, selfie comparison, fraud checks and liveness checking in an automated identity-verification operation. It detects fake or altered identity documents and compares a selfie with the document photo using 1:1 face verification. Kairos says its document coverage includes 4,000 passport and ID types from more than 190 countries. A single selfie is used to check that the image was captured live and deter spoofing. Developers can integrate the API using any programming language, while users can also upload selfie images and identity documents through the web interface for manual verification. Kairos says face images are masked as templates, stored data is encrypted with AES-256, and TLS protects data in transit. Its described security controls include role-based access, audit trails, monitoring, firewalls, masking and tokenization. The free plan includes 100 API transactions and a two-week trial. Pro costs $49 a month and includes 100 API calls; an on-premise option has pricing on request.

Microblink BlinkID extracts information from identity documents for workflows such as digital onboarding, age verification, check-in, visitor management, and KYC and AML compliance. It supports more than 2,500 document types from over 140 countries, and the maker says its machine-learning capture and extraction models support Latin, Cyrillic, and Arabic characters. Capture detects a document when image quality is sufficient; checks cover document data, liveness, manipulation, and integrity signals. Documentation says extraction happens on the device and document data does not leave it. Integration options include SDKs for TypeScript, Kotlin, Swift, React Native, and Flutter, a C SDK for desktop apps and custom hardware, and a self-hosted API that can run alongside a customer backend. The product supports Android, iOS, Linux, macOS, web, and Windows, as well as API and self-hosted deployments. Microblink offers a 30-day trial with unlimited scans. There is no free plan; pricing is available on request for a custom plan.
