Account Information Services (AIS) refer to services that provide users with access to their financial account data. These services allow individuals and businesses to view their account balances, transaction history, and other relevant financial information from various financial institutions in one place. AIS can help users manage their finances more effectively by consolidating data and offering insights. Typically offered by fintech companies or banks, AIS can enhance user experience through features like budgeting tools and spending analysis. By securely connecting to multiple accounts, these services aim to simplify financial management and improve decision-making for users.
