An Account Information Service (AIS) is a regulated open banking service that enables a licensed third-party provider – known as an Account Information Service Provider (AISP) – to access and consolidate financial account data from one or more banks or payment institutions, with the explicit consent of the account holder. AISPs operate under the Payment Services Directive 2 (PSD2) regulatory framework in Europe, which requires them to be authorised by a national competent authority (such as the FCA in the UK or any EU member national competent authority) and to access account data exclusively through standardised, secure open banking APIs. The account holder retains full control; they can grant or revoke access at any time.
As illustrated in a typical Account Information Service data flow, a user connects their bank accounts to an AISP-powered application by authenticating directly with their bank through a secure redirect or embedded consent journey. The bank – acting as the Account Servicing Payment Service Provider (ASPSP) – shares the requested account data via its open banking API. The AISP retrieves and consolidates this data – including balances, transaction history, and account details – and presents it within its own platform. No payment is initiated and no funds are moved; AIS is a read-only service.
Key Takeaways: #
- An Account Information Service (AIS) is a regulated open banking service that aggregates financial data from multiple bank accounts into a single interface, with the account holder’s explicit consent;
- Account Information Service Providers (AISPs) are authorised and regulated under PSD2 in Europe (and equivalent frameworks in other jurisdictions) and must be licensed by the relevant national competent authority;
- Common use cases include personal finance management, business cash flow monitoring, creditworthiness assessment for lending, and data-driven financial product personalisation.
How Account Information Services Are Used #
Personal Finance Management: AISPs power personal finance management (PFM) applications that aggregate data from multiple bank accounts into a single dashboard. Users can monitor balances, track spending patterns, categorise transactions, and set budgets across all their accounts without logging into each bank separately. Applications such as open banking-powered budgeting tools rely on AIS as their core data layer.
Business Cash Flow and Treasury Monitoring: For businesses operating accounts across multiple banks or entities, AIS provides a consolidated, real-time view of cash positions, incoming and outgoing transactions, and account balances. This is particularly valuable for finance teams managing liquidity across multiple currencies or legal entities, reducing the manual effort of reconciling data from separate banking portals.
Creditworthiness and Affordability Assessment: AISPs are increasingly used by lenders to assess an applicant’s creditworthiness and affordability directly from their transaction history. Rather than relying solely on credit bureau data or self-reported income, lenders can – with the applicant’s consent – access real transaction data to evaluate income patterns, regular outgoings, and financial behaviour, enabling faster and more accurate lending decisions.
Financial Product Personalisation: By analysing transaction data, AISPs enable financial platforms to offer personalised product recommendations – such as savings accounts, insurance products, or investment options – based on a user’s actual financial behaviour rather than generic demographic profiles.
Automated Expense Categorisation and Reporting: AIS data feeds into accounting and expense management platforms, enabling automatic categorisation of business transactions, VAT identification, and financial reporting. This reduces manual bookkeeping effort and supports real-time financial oversight for businesses of all sizes.
FAQ: #
Is it safe to connect my bank account to an Account Information Service Provider?
- AISPs are regulated and must be authorised by a national competent authority before they can access account data. Under PSD2, they are required to access data exclusively through secure, bank-approved open banking APIs – they cannot store a user’s banking credentials. Users can verify whether an AISP is authorised by checking the relevant national register, such as the FCA register in the UK or the EBA register in the EU. Consent can be revoked at any time through either the AISP platform or directly through the user’s bank.
What is the difference between an AISP and a PISP?
- An AISP (Account Information Service Provider) is authorised to read account data only, it cannot move funds. A PISP (Payment Initiation Service Provider) is authorised to initiate payment transactions directly from a user’s bank account on their behalf. Both are regulated under PSD2 and require explicit user consent, but they serve distinct functions: AISPs provide financial visibility, while PISPs enable payment execution.
