London-based payments firm Finsei has picked issuer processing platform Thredd to power its new Mastercard debit offering.
“The partnership reflects a shared focus on simplifying an increasingly complex payments environment,” Thredd said in a Tuesday (Oct. 20) news release. “Businesses operating across markets often rely on multiple providers to manage accounts, payments, foreign exchange, cards and expenses.”
Finsei aims to bring those capabilities together, while Thredd offers the underlying payment technology and infrastructure needed to deliver a “secure, digital-first debit experience at scale,” the release added. Physical and virtual cards will be available at launch, with Apple Pay and Google Pay due to follow.

“Businesses increasingly expect their financial tools to work together rather than operate as a collection of disconnected services,” said Jim McCarthy, CEO of Thredd.
“Finsei is building around that expectation, bringing payments, currency management and business spending into a more unified experience. Thredd’s role is to provide the flexible, resilient infrastructure behind the card proposition so Finsei can focus on delivering the simplicity, control, and experience its customers expect.”
With this partnership, Thredd will provide Finsei with payment processing and automated back office capabilities, along with services such as tokenization, push provisioning, and 3D Secure and fraud transaction monitoring.
“Our clients run businesses across borders, and they don’t want one provider for accounts, another for FX and a third for cards,” said Artjoms Dozorcevs, CEO of Finsei. “Building our debit card proposition on Thredd’s infrastructure means a payment received in one currency can be spent in another from the same account, with the security controls our clients expect. Thredd gives us room to expand what our cards can do as our clients’ needs grow.”
In other debit news, recent PYMNTS Intelligence research, from the report “The Incremental Imperative: Why Debit Innovation Is the New Standard for Cardholder Loyalty,” indicates that debit’s next chance for growth is closely related to younger consumers’ expectations.
“Gen Z consumers are entering adulthood with a different relationship to money than previous generations, using debit as both a spending method and a budgeting tool,” the report said. “Their preference is not simply about avoiding credit and its associated debt. It reflects a broader demand for immediacy, visibility and control over money movement.”
That preference can be seen at checkout, the report added, with PYMNTS Intelligence research showing that Gen Z consumers are debit-first at the grocery store, with 42% using debit, versus 19% who use credit and 6% turning to Apple Pay.
