Banks & Fintech

Banking technology covers the systems a bank runs to hold accounts, lend, move money and meet regulatory obligations, including core banking, payments and credit decisioning, and the partnerships through which fintechs offer banking services.

Start with the operating model: who owns the account, the customer relationship and the decision? Follow the guides through core selection, credit scoring, consent and bank partnerships. The banking and credit reading path connects these decisions; Railspan separately illustrates a proposed implementation with synthetic examples.

PRACTICAL READING PATHS

Start with the question you need to answer.

Choose the work in front of you. Each path moves from a starting question to a practical decision, with examples you can adapt. Project experience is documented separately in the case studies.

◆ Questions

Common questions about Banks & Fintech.

What is a core banking system?

A core banking system is the bank's system of record for customer accounts, balances, deposits, loans, interest and transaction posting. Mobile apps, payment systems and other channels rely on it for the authoritative balance.

What is a sponsor bank?

A sponsor bank is a licensed bank that provides accounts, card programmes or payment access for a fintech that does not hold its own banking licence. The bank remains responsible to its regulators, so it requires the fintech to meet its compliance, record-keeping and reconciliation standards.

Does a fintech need a banking licence?

Not always. Many fintechs operate through a partner bank or under a narrower payments or e-money licence, depending on whether they hold customer funds and in which jurisdictions. The answer depends on the flow of funds and local law.
