How we automated the processing of thousands of daily documents?

The road to a more efficient and secure operation

A major banking institution sought to improve operational efficiency across its network of over 150 branches.

At the time, check processing was still conducted manually: each check was scanned, bagged, and physically transported daily to a central unit for validation and processing. This approach resulted in high logistical costs, a significant risk of errors, tight timelines for compliance with current regulations, and strong operational dependencies.

In response, we proposed the development of a secure, scalable, digital solution that would decentralize the check scanning, validation, and transmission process at the branch level—eliminating physical transport and enhancing overall operational efficiency.

A hybrid architecture for a more agile process

We designed and implemented a hybrid architecture based on desktop software, web applications, and cloud services to enable the distributed and secure digitization of checks.

Key components:

• Local scanning app (ElectronJS + .NET Core executables): Installed at each branch, the app provides a unified interface to operate physical scanners, regardless of brand or model.
• Web-based backoffice app (React + Material UI): Allows teams to review, validate, and monitor daily operations in real time, with a highly intuitive user experience.
• AWS Cloud Infrastructure: A serverless architecture leveraging services like Lambda, Rekognition, S3, DynamoDB, AppSync, Cognito, and WAF for scalability and security.
• Integration with on-premise systems: Including Active Directory, ATRIL, Daily Deposits, and internal APIs for data preloading and account validation.

Digitization at scale: 150+ branches in production

The development was completed in record time:

• A proof of concept was initiated in mid-December.
• By February, functional demos were being conducted.
• The system went live in April, and has operated continuously since then without major incidents.

The solution was deployed across 100% of the branch network (150+ locations), fully compatible with existing operating systems and optimized to function efficiently even in low-connectivity environments.

Transforming a mission-critical process

Since deployment, the system has enabled the digitization of 2,000 to 3,000 checks per day across the branch network, with minimal workload for local teams. The project was completed in just three and a half months—including development, testing, and go-live—meeting tight deadlines without compromising quality.

One of the most impactful outcomes was the elimination of all physical document transport. This not only reduced operating times and logistics costs, but also enabled real-time validation of each check at the moment of submission—improving both speed and reliability.

Technically, the system was designed to operate under limited network conditions, a common scenario in remote branches. This was essential for delivering reliable performance without requiring additional infrastructure.

The client expressed high satisfaction with the delivered product. In on-site meetings, both the stability and robustness of the solution were praised, along with its ability to automatically resolve the vast majority of use cases. For checks that couldn't be scanned due to damage or print issues, the system allowed manual entry with warnings—without disrupting the operational flow.

The user experience was tailored to accommodate different roles—from branch staff who perform the initial uploads, to backoffice teams who consolidate and process the data. Since launch, the platform has remained stable and continues to serve as a key asset in the client’s modernization strategy.

Digitizing thousands of documents daily without losing efficiency or security

Digitizing the check management process across more than 150 branches was not only about improving operational efficiency—it also demanded high standards for security and compliance. From day one, the solution was designed to ensure reliability, traceability, and control at every stage, enabling the process without compromising data integrity or validation.

Close collaboration between our technical team and the client made it possible to deliver a modern, serverless cloud architecture that adapted seamlessly to real-world conditions. Its stability in production, ease of use, and lack of critical incidents demonstrate the robustness of the implementation.

This case shows how a traditional operational challenge can be solved with modern architecture, combining desktop applications, cloud-native services, and a user experience tailored to real-world environments.
