What does open banking mean for customers?

You may wonder what the  open banking API meaning  is for customers. Open banking allows online payments to be more streamline for consumers, who are able to give permissions for online merchants to access funds directly from their bank accounts using an integrated payment API. Those with more than one account are able to access all their financial information and data in one place, using an account information service provider (AISP). Third party service providers will need to be authorised and comply with the PSD2 regulations. As a result, consumers are more protected. PSD2 leads to better authentication processes and better protection against fraud.


Thanks to PSD2 and AIS, banking transactions that used to be paper-based are now able to be digitalised. Digitalisation benefits consumers by simplifying processes that spare time and effort. For example, consumers no longer have to tediously send and receive account statements, salary slips and other documents needed for credit checks when applying for a loan. Once consent has been granted by the consumer, the lending institute receives all the relevant information from an AISP. This information is already analysed and aggregated. This process empowers consumers to have control over their bank data and allows them to make informed decisions about which third party PSD2 providers  can access their data.

Account Information Services (AIS) are able to leverage open banking data in order to improve their customer service as well as consumer satisfaction. AIS can use the enriched data to gain insights into spending behaviours and financial health of their consumers and offer customised services and suggestions that are tailored to specific consumer needs. consumers are again empowered as they can pick and choose between services and decide what ’s best for them.

Is open banking mandatory?

The PSD2 directive that aims to promote the development and use of innovative online and mobile payments through open banking. While it is mandatory for banks to facilitate open banking it is not mandatory for bank customers to participate in open banking applications and services.


As of the 13 of January 2018, PSD2 has been legally required in the EU and EEA. PSD2 officially went into effect on September 14, 2019 but due to the amount of technical difficulties and delays, banks, merchants and other institutions were granted an extension for full implementation to the end of 2020.


There are two ways for businesses to comply with PSD2. Firstly, platforms can apply for a licence to either become an account information PSD2 service provider  (AISP) or a payment initiation service provider (PISP). Both types of solutions are known as third-party solutions. They gain access to open banking data securely and with the consent of consumers. AISPs have "read-only "access to a consumer 's bank account, whereas PISPs have "read-and-write "access. Businesses can also use other payment service providers, like AISPs or PISPs.

It has made it easier for new market entrants and payment institutions to gain access to the market and thus increased competition and choice for consumers. Payments are now easier and quicker in all payment services directive countries .

PSD2 has three main benefits- increased consumer rights, improved security and permission for third-parties to access payment account information.
