Fintech Vocabulary in English

Fintech is a portmanteau of financial technology. It refers to companies and innovations that use modern technology — such as mobile apps, artificial intelligence, and blockchain — to deliver or improve financial services. Examples include mobile payment apps, online lending platforms, robo-advisers, and digital-only banks. The term is used widely in business journalism and is important vocabulary for anyone studying economics, business, or technology in English.

A neobank (also called a challenger bank) operates exclusively through a mobile app or website — it has no physical branches. Traditional banks have a network of branches where you can speak to staff in person. Neobanks typically offer lower fees, faster account opening, and real-time spending notifications, but they may have fewer products. Traditional banks often have more services such as mortgages, business banking, and face-to-face advice. In the UK, well-known neobanks include Monzo and Starling.

Open banking is a system in which banks are required (or permitted) to share customers’ financial data securely with approved third-party companies, provided the customer gives their consent. In the UK, open banking was introduced following a 2016 regulatory requirement. It works through APIs — standardised connections that allow apps to read your account data. This means you can use a single budgeting app to see all your bank accounts in one place, or allow a lender to check your real income before approving a loan.

A digital wallet is a software application, usually on a smartphone, that stores your payment card details and allows you to pay for goods and services without using a physical card. Examples include Apple Pay, Google Pay, and Samsung Pay. When you tap your phone against a card reader, the wallet uses near-field communication (NFC) technology to transmit a secure token rather than your actual card number, making the payment both convenient and relatively safe from fraud.

KYC stands for Know Your Customer. It is a process that financial companies use to verify the identity of their clients before providing services. In fintech, this often means uploading a photo of your passport or driving licence and a selfie when you sign up for an app. KYC is required by law to prevent money laundering, fraud, and the financing of criminal activity. Although it can feel like a barrier, it protects both the company and legitimate customers by ensuring that accounts are not opened under false identities.

A regulatory sandbox is a controlled environment created by a financial regulator — such as the Financial Conduct Authority (FCA) in the UK — that allows fintech companies to test new products and services under special conditions. Inside the sandbox, certain rules are relaxed so that companies can innovate without needing full regulatory authorisation. If the product works safely, the company can then apply to operate in the full market. The sandbox model has been widely copied by regulators around the world.

Most cryptocurrencies, such as Bitcoin or Ethereum, have prices that can change dramatically from day to day, making them risky as stores of value. A stablecoin is a type of cryptocurrency designed to maintain a stable price by being pegged to a conventional asset such as the US dollar or gold. For example, one unit of a USD-pegged stablecoin should always be worth approximately one US dollar. Stablecoins are used by traders who want to stay in the crypto ecosystem without exposure to wild price swings.

Peer-to-peer (P2P) lending is a form of borrowing and lending that takes place through an online platform, cutting out the traditional bank as an intermediary. Borrowers apply for loans on the platform, and individual investors provide the money in exchange for interest payments. Because the platform has lower overheads than a bank, borrowers can sometimes get lower rates and investors can earn higher returns than they would from a savings account. However, P2P lending carries risks: if a borrower defaults, the investor may lose their money.

In the context of payments, tokenisation is the process of replacing your actual card number or bank account details with a unique digital code called a token. When you pay by phone or via a website, the token is transmitted rather than your real card details. Even if a criminal intercepts the token, it is useless without the matching cryptographic key held by the payment processor. Tokenisation is one of the main reasons that contactless and digital-wallet payments are considered very secure.

Embedded finance refers to the integration of financial services — such as payments, loans, insurance, or savings — directly into non-financial apps, websites, or platforms. For example, when you buy something online and are offered “buy now, pay later” at the checkout, that is embedded finance. When a food-delivery app lets you tip the rider instantly, that is embedded payments. The idea is that financial services become invisible and frictionless, built into the products and platforms people already use every day.
