Choosing an ID scanning solution for KYC is not an easy decision. Different industries, regulatory environments, and onboarding models create different requirements for document processing. A high-growth fintech onboarding customers at scale, a telecom operator verifying SIM registrations, and a government service portal may all approach ID verification for KYC differently.
Sumsub has established itself as a recognized provider of identity verification solutions. At the same time, many organizations are evaluating alternatives that offer greater flexibility, stronger control over document data, and document recognition capabilities that can be integrated directly into existing workflows.
Sumsub is a cloud-based platform that provides identity checks, transaction monitoring, and case management within a single onboarding infrastructure. Sumsub is an established player in the market. The platform allows organizations to build end-to-end customer verification processes.
At the same time, every organization has unique requirements, and a solution that works well for one business may not be the ideal fit for another. Cloud architecture can also introduce trade-offs related to infrastructure control, data processing, and workflow flexibility. It also means that document processing is typically tied to vendor-managed infrastructure and cloud-based workflows. As a result, companies frequently evaluate alternative providers to identify the technology that best aligns with their operational, technical, and financial goals. In particular, one that supports a wide range of document types and offers a higher level of security.
Why Businesses Are Looking for Sumsub Alternatives
The growing demand for alternatives to Sumsub is driven by several practical business considerations.
Privacy and Data Protection Considerations
As privacy regulations continue to evolve worldwide, many organizations are reviewing how customer documents are processed during identity verification. Businesses prefer solutions that minimize the transfer of sensitive document images and data to third-party servers and provide greater control over personal data throughout the verification process. These considerations can be particularly important for banks and other fintech organizations operating in highly regulated sectors.
Real-world Capture Conditions
Real-world identity verification rarely happens under ideal conditions. Users may submit documents captured in poor lighting, with motion blur, perspective distortions, or partially visible fields. Businesses also need to process and detect photocopies, scan multiple documents within a single image. As a result, organizations evaluate providers based on their ability to maintain high OCR accuracy across challenging document types and capture conditions.
Support for secure Zero-Trust KYC workflows
Each additional system involved in KYC introduces another potential point of exposure for sensitive data. By enabling fully client-side document processing in the browser, document images do not need to be sent to external services and crowdsourcing platforms. This reduces security risks, strengthens privacy, and supports compliance requirements.
Advanced fraud detection
Identity fraud has moved beyond traditional document forgery. Digital forgeries, presentation attacks, and deepfakes can target both physical and digital identity credentials, making fraud detection more difficult than ever.
Companies need solutions that provide multiple layers of protection. This includes digital forgery detection, deepfake detection, document security feature checks, presentation attack detection, and cross-verification of document data from VIZ, MRZ, and RFID. The ability to detect sophisticated fraud while maintaining a smooth onboarding experience is an important factor when evaluating identity verification providers.
Faster Integration and Global Document Support
Modern onboarding journeys take place directly within websites and web applications. The ability to implement secure web ID scanning capabilities within a company’s own digital environment can improve both development efficiency and customer experience.
Once deployed, the solution must reliably process documents issued across dozens of countries and jurisdictions. Beyond standard passport scanning and national ID verification, companies may require support for multiple writing systems, including Arabic OCR, Cyrillic, Chinese, Korean, Japanese and other Asian languages.
Why OCR Studio Is a Strong Alternative to Sumsub
OCR Studio is a developer of advanced ID scanning and verification technologies for digital onboarding and KYC workflows. Its solution is designed to capture, scan, and extract data from ID cards, passports, driving licences, and other identity documents, even when standard OCR systems often struggle.
OCR Studio supports on-premises, on-device, and fully client-side processing. Organizations can ensure speed and accuracy of KYC within a controlled environment – without relying on external platforms or cloud-based services.
The technology supports passports, national IDs, driver’s licenses, residence permits, bank cards, and other document types from more than 250 countries and issuers. Particular attention is given to multilingual and multiscript recognition, including Arabic OCR, Persian, and CJK documents.
OCR Studio is built for real-world capture conditions – delivering reliable onboarding capabilities across mobile and web applications:
Complex use-cases – photocopies, multiple documents in one frame, one-shot KYC. One-shot KYC enables document data extraction and face matching using a single image.
Complex documents – old blanks, worn-out, booklets, etc.
Beyond document scanning, OCR Studio also includes advanced fraud detection capabilities. The technology can detect digital forgeries, deepfakes, and presentation attacks, while cross-checking information across VIZ, MRZ, NFC, and other document elements.
Organizations can integrate OCR Studio through a web OCR SDK for KYC workflows in web – without being constrained by predefined onboarding scenarios. The solution performs recognition and extraction locally through WebAssembly-based technology, which makes it particularly attractive for companies that require greater control over data handling.

As onboarding workflows become more complex and privacy requirements continue to evolve, document recognition technology itself is becoming a strategic consideration. Beyond verification outcomes, businesses focus on data handling, deployment flexibility, and the ability to process documents reliably outside ideal conditions. These factors can influence everything from compliance and security to onboarding speed and operational efficiency.
Where OCR Studio Delivers More Value
OCR Studio offers several advantages that make it a strong alternative for businesses seeking efficient document OCR and ID verification for KYC capabilities.
Client-side processing ensures that document recognition takes place directly on the user’s device. No document images need to be transferred to external OCR services simply to perform ID verification for KYC. This approach reduces personal information exposure risks and helps businesses maintain compliance with privacy and data protection regulations.
OCR Studio provides businesses with the flexibility to build verification workflows around their own operational requirements. Organizations can integrate OCR Studio through a web OCR SDK, mobile SDK, desktop SDK, making it easier to adapt document processing to existing systems, mobile apps, web platforms, and more.
