What is banking aggregation?

In general terms, bank aggregation is a service that allows the automatic collection of account and customer information in the banking sector. This information can then be made available to other institutions under certain conditions of use in order to offer a better service.

It is a method of information management that is part of the current open banking trend. So we ensure that it meets the requirements of transparency and access to information. These technologies comply with certain regulatory parameters and fall within the European regulations of the Revised Payment Services Directive or PSD2.

How does bank aggregation work?

The way banking aggregation works is less complicated than it sounds. Customer information, such as their accounts, transactions, payments and finances, is associated with a single account holder and presented in a single interface. This allows the customer to view all their financial information on a single platform.


This type of service is possible because the user gives access to third parties so that they can use certain information and, in this way, improve their services and business performance. This is achieved thanks to application programming interfaces (APIs), which are software products needed to manage bank accounts and operations.

Explanation of bank aggregation

In summary, banking aggregation is a service that seeks to improve the management of and access to customers’ financial information in the banking sector. By allowing access to third parties, it promotes innovation and the development of new financial services. In addition, this service complies with the regulatory requirements established by the European PSD2 regulation.


For the user, the banking aggregation allows customers to consult all their accounts in a single app.

PSD2 and banking aggregation

The so-called Account Information Service (AIS) offers the possibility to lend the information to third parties at your discretion. The owners of the information must give their explicit consent and can withdraw it at any time.

As this generally involves bulk data from a multitude of accounts from which the liquidity, purchasing habits or degree of indebtedness of a certain demographic group can be ascertained, the information is catalogued using the protocols established by the European Union’s revised Payment Services Directive (PSD2).

Banking aggregation softwares

There are many banking aggregation softwares that employ different verification, cataloging and geolocation protocols for data collection. These collect data from banks, accounts, credit cards, personal data and financial services, among many others, within the same organized platform.

There are two types of protocols used to establish banking aggregation: PIS payment aggregators and AIS information aggregators.

New call-to-action

Payment aggregators (PIS)

Payment Initiation Services (PIS) are protocols for collecting data from payment transactions that customers perform on a regular basis.

They are present in most payment and transfer services, improving the operational performance of the platforms in terms of billing, receipt and payment methods.

Information aggregators (AIS)

On the other hand, AIS -Account Information Services- collect a wider range of information that allows banking information to be optimized according to other demographic variables.

Both technologies make it possible to study the risk associated with financial services and gain a better understanding of how customers spend their money.
