Innovation in Card Processing with AWS: the Unicred + Zallpy case

The challenge: modernizing the card processing system

Unicred, one of Brazil’s largest credit cooperatives with more than 248,000 members, set out to modernize its credit card processing system.

In 2019, the institution decided to launch its own card, aiming to gain greater operational control, autonomy, profitability, and innovation. To achieve this, it was essential to adopt a cloud-based infrastructure that ensured security, scalability, and state-of-the-art technology.

The solution: cloud infrastructure powered by AWS

Zallpy was selected as the project partner due to its expertise in cloud solutions and deep knowledge of the AWS ecosystem.

With a product and business-first approach, prioritizing business needs before technology choices, the Zallpy team led the integration of the new infrastructure using services such as:

• Amazon EKS
• Amazon CloudWatch
• Amazon RDS
• Amazon DynamoDB
• AWS Lambda
• Amazon EC2

The development lasted seven months and involved multiple professionals and vendors, with Zallpy playing a central role in coordination and technical implementation.

The results: efficiency, scalability, and innovation

The transition to AWS cloud infrastructure delivered significant results for Unicred:

• A new infrastructure capable of processing payments for more than 100,000 member cards.
• Real-time transactions and the ability to scale the number of cards without impacting physical infrastructure.
• A 75% cost reduction compared to the previous on-premises structure.
• Strengthened positioning of Unicred as an innovative financial institution and a reference among credit cooperatives.
• Improved customer experience through high availability and reliability.

This project marked a milestone in Unicred’s digital journey, establishing a strong foundation for future innovations and technological transformations in the financial sector.
