What is fintech?

At its simplest, a fintech replaces or improves one financial process. A digital bank offers a fee-free account through an app with budgeting tools built in, using mobile, cloud and APIs instead of a branch network. A payments API runs on cloud infrastructure, uses cryptography for security and plugs into merchant systems. An online lender uses bank feeds and AI-driven credit scoring to make decisions faster than a paper application allows.

The business models are just as varied: merchant and interchange fees for payments, subscription or software-as-a-service charges for RegTech and business finance tools, the lending spread for marketplaces and digital lenders, and revenue-share or referral fees for embedded finance inside retail and software platforms. Banks tend to collaborate rather than compete head-on, partnering with fintechs through APIs and distribution agreements, white-labelling their technology, or acquiring them outright.

Lending marketplaces connect consumers and small businesses with a panel of lenders and earn origination and servicing fees. AI and machine learning drive credit scoring, fraud detection and personalised pricing, and alternative credit scoring models reach customers who would not pass a traditional assessment. Embedded credit at the point of sale reduces friction for merchants and shoppers, which is what lifted buy now, pay later into the mainstream.

Connected devices play a part too: telematics feed usage data into fleet finance and usage-based insurance. For brokers, the practical effect is faster decisioning, digital document collection and e-signing, and lenders that can verify income and expenses straight from bank data instead of paper statements. The trends to watch are embedded finance, AI-driven personalisation, green fintech and automated compliance and reporting.

A fintech is regulated according to what it does. ASIC oversees financial services licensing and consumer protection, so it may need an Australian Financial Services Licence (AFSL), an exemption, or a credit licence for lending. APRA authorises deposit taking institutions, so a fintech that wants to hold customer deposits and call itself a bank needs an APRA authorisation or must operate under another ADI's licence. AUSTRAC covers anti-money laundering obligations for payment providers and exchanges, including customer due diligence and suspicious matter reporting. The RBA oversees payments infrastructure, the ATO the tax treatment of digital assets and business income, and the OAIC the Australian Privacy Principles.

Before using a fintech, ask for its licence or registration number and check it on ASIC's register and AUSTRAC's lists. Red flags are a provider that will not share licensing details, promises of unusually high returns, opaque fees, and pressure to move money outside normal channels. Strong authentication, clear data-handling policies and independent audits are the signs of a provider that takes security seriously.
