PSD2 (Payment Services Directive 2)

An EU legislative framework (PSD2, Directive 2015/2366) governing payment services and payment service providers across the European Economic Area. PSD2 introduced requirements for strong customer authentication, mandated open access to payment account data for authorised third parties (enabling open banking), and created new categories of regulated payment institutions.

Firms that provide specialist knowledge-based services such as consulting, engineering, IT services, legal advisory, and financial analysis. KIBS firms are characterised by high intangible asset intensity, with the majority of their enterprise value derived from human capital, client relationships, proprietary methodologies, and reputation.

A regulatory and technological framework that enables third-party financial service providers to access consumer banking data through secure APIs, with the customer's explicit consent. In the UK, open banking was mandated by the CMA's Open Banking Remedy (2018) and is governed by the Open Banking Implementation Entity.

A financial institution licensed by card networks to issue payment cards (credit, debit, or prepaid) to consumers and businesses. The issuing bank extends credit or provides access to deposited funds, bears the cardholder's credit risk, and receives interchange fees on each transaction.

The integration of financial services — such as payments, lending, insurance, or investment — directly into non-financial platforms and customer journeys. Embedded finance enables companies like e-commerce platforms, SaaS providers, and gig economy marketplaces to offer financial products without becoming licensed financial institutions, typically through Banking-as-a-Service partnerships.

A financial ecosystem built on blockchain technology that provides financial services — including lending, borrowing, trading, insurance, and asset management — without traditional intermediaries such as banks, brokerages, or exchanges. DeFi protocols use smart contracts to automate financial transactions and are typically open-source, permissionless, and composable.

A fee paid by the acquiring bank to the issuing bank each time a payment card transaction is processed, representing the largest component of the merchant discount rate. Interchange fees are set by card networks (Visa, Mastercard) and vary by card type, merchant category, transaction method (card-present vs card-not-present), and jurisdiction.

The EU regulatory framework (Regulation 2017/745) governing the design, manufacture, and distribution of medical devices in the European market, which replaced the Medical Devices Directive (93/42/EEC) with significantly stricter requirements. MDR imposes enhanced clinical evidence requirements, more rigorous conformity assessment procedures, a Unique Device Identification system, and comprehensive post-market surveillance obligations.
