Revolutionizing Digital Payments and Loyalty

Organizations across every industry and around the globe rely on Couchbase to build fast, resilient, and scalable applications. More than just a database, Couchbase supports complex queries, real-time updates, and high-performance scalability – enabling everything from modern enterprise systems to AI-powered applications and agentic architectures.

Throughout the day, people often engage with dozens of Couchbase-powered applications, often without even realizing it. From checking mobile apps first thing in the morning, to buying coffee, tracking health data, making payments, receiving fraud alerts, booking travel, streaming content, and playing games. In many cases, Couchbase customers work in tandem to deliver seamless, personalized experiences for users. One example of this in action is Wollette and Tesco.

Wollette: revolutionizing digital payments and loyalty

Wollette is an innovative fintech company focused on redefining commerce through an innovative agentic commerce platform and revolutionary contactless account-to-account payments. Wollette’s platform enhances consumer commerce experiences by offering businesses seamless, cost-effective payment processing and personalized loyalty programs. Their solutions address the need for faster, more secure payment methods and offer businesses valuable insights into customer behavior while promoting environmental sustainability through digital receipts.

Wollette values both merchants and consumers. Merchants realize cost savings and ease of management as Wollette brings multiple tools together all in one place, instead of having to go to different suppliers. The merchants pass on some of these savings to consumers as a way to attract them, which in turn increases revenue.

The company’s key challenge was meeting the demand for real‑time, secure, scalable payment processing while simultaneously supporting loyalty programs and customer analytics via JSON‑based profiles. They needed a backend that could handle high transaction volumes efficiently and deliver personalized insights without compromising speed or reliability. Wollette turned to Couchbase to enable real‑time payment processing and massive data scalability without sacrificing performance. As a result, Wollette was able to reduce transaction processing times by 5x, enabling real-time, seamless payments in the Open Banking space.

One of these merchants that has partnered with Wollette to streamline payments and create a better customer experience is Tesco.

Managing millions of products at the world’s third-largest retailer

Tesco utilizes Couchbase for profile management and session stores, scaling easily to support tens of millions of products in-store and online and 35K requests per second for millions of customers. With Couchbase, Tesco can easily deliver a superior shopping experience even during high-demand periods like Black Friday. The company runs price and promotions, inventory management, shopping cart, supply chain, and new product applications with high performance and high availability.

Tesco customers can leverage Wollette for one tap payments at checkout, plus personalized rewards and discounts. Couchbase is at the heart of this partnership, providing superior querying and indexing capabilities, along with its support for multi-dimensional scaling. This helps store and manage large volumes of data, ensuring that both payment and loyalty data is processed quickly and securely. The ability to store JSON documents with direct embedding support enables Wollette to efficiently manage customer profiles and transaction details, improving both data retrieval times and overall system performance.
