Pismo's upgraded system supporting 3,000 TPS per account

Pismo, a global cloud-native core banking and card processing provider, has announced a significant enhancement to its core authorisations engine. The upgraded system now supports over 3,000 concurrent transactions per second (TPS) for each customer account, a tenfold increase from the previous version.

This enhancement aims to meet the needs of large business customers who require high levels of throughput, availability, and scalability.

It's designed to support organisations during high volume traffic surges, payroll periods, and other critical operations. The company plans to upgrade all clients over the next six weeks.

Juliana Binatti, co-founder and Chief Product Officer at Pismo, commented on the importance of the ledger in a banking system. "The ledger is the heart of a banking system. It manages account balances and limits, keeps track of the change in account balance, and validates if an account has enough balance for a transaction. Speed and accuracy are pivotal," she said.

"By offering a streamlined system that can handle 3,000+ simultaneous transactions per second in every single account, we are giving our clients the peace of mind to deal with traffic surges, helping them improve their client's experience."

The platform update took 18 months to develop, encompassing research, development, and extensive testing phases. Pismo tested the enhanced ledger with the participation of a Tier 1 banking client. The rollout for current clients will occur over the next two months, while new clients will be onboarded with the new functionality immediately.

Adopting a best-in-class continuous delivery process, Pismo performs more than 400 deployments on its platform monthly.

This approach allows the company to offer regular security and performance enhancements, as well as new features, without affecting the platform's 99.99% uptime. Clients will not need to take any action and will benefit from the latest update with full transparency.

Pismo processes more than 108 million accounts and has its headquarters in Brazil, with additional offices in the UK, US, India, and Singapore.

The company, which operates with over 500 employees, provides broad product coverage, including core banking, payment processing, card issuing, digital wallets, lending, transaction banking, and financial asset management functionalities.

Following its acquisition by Visa International in January 2024, Pismo continues to work with leading card networks while remaining network agnostic.
