The platform, which connects banks with complementary fintech solutions, such as Codat, Tink, Taurus, and Wise, is used by around 3,000 financial institutions globally.

Paymentology’s payment processing platform, which is popular with many of the challenger banks, including Revolut and Standard Chartered's Mox Bank, runs card programs that track and control users’ spending cycles on an evermore granular level. Temonos’ collaboration with the London Victoria-based fintech enables its banking clients to plug into the hot buy-now-pay-later (BNPL) services that big techs such as Apple and Google have been keen to exploit in the battle for the consumer marketplace.

The new Swiss-UK partnership is promising real-time data feeds with access to over 120 lines of data associated with any given transaction, compared with the 10 to 20 lines of data associated with many legacy systems. This forensic level of transaction tracking is arguably the Golden Ticket for banks to upsell a surfeit of financial products and services to customers.

“This capability allows banks to understand their customers' behaviour and requirements better. It also empowers banks to launch more effective card programs based on more granular, calculated, data-driven decisions,” the parties said.

"We share a commitment to helping banks know their customers better and deliver a better service through data and digitisation. Together, we are helping banks better support the customer spend journey via AI-enabled data analytics, meaning they can offer service solutions for debit, credit, prepaid and commercial cards," CEO at Paymentology, Abe Smith, said.

Martin Bailey, product director at Temenos, added: "We are opening up this capability to our clients worldwide, enabling them to deliver innovative payment experiences much faster. In today's hyper-competitive payments market, this ability is vital for banks to differentiate and stay ahead of the curve."
