Nowadays, operations that previously required to go to the bank have been replaced by mechanisms that allow transactions to be carried out from anywhere. But what if it were possible to go further? What if there were a way for all customer needs to be met through applications?

This and much more is what Open Banking brings with it. Its emergence has given rise to numerous unknowns for customers, bank owners and entrepreneurs alike. Want to know what it’s all about and what the advantages and disadvantages of online banking are? We’ll tell you right away.

What is Open Banking?

Open Banking is a little-known concept, due to its poor implementation by the banking system and the lack of customer education about it.

“Generally speaking, it is a mechanism in which customer banking information is shared to applications or APIs. In this way, an ecosystem is created that is conducive to generating business, solving needs, suggesting services and much more.”

Open Banking requires data related to credit cards, statements, and account types and everything that includes the customer’s finances. Once ready, this information is synchronized with the various emerging applications and starts an exchange process that facilitates the life of anyone thanks to the bank.

Of course, there are many advantages and disadvantages of online banking. The evaluation of them is what has generated many questions for its global application.

Disadvantages of Open Banking

Some of the drawbacks of Open Banking are:

  • Low customer credibility: until now there has been an apathy or lack of credibility on the part of customers towards Open Banking. It is partly due to the fear of sharing their data, as well as to their lack of knowledge of how it works.
  • The Fintech: the growth of those companies that have replaced the banks is a major drawback for Open Banking. The Fintech market is growing. Their services are diverse and more and more there are a large number of them in all countries. They are simple, fast and do not generate so many expenses for customers.
  • It removes the interpersonal relationship with the customer: because everything is handled digitally, the face-to-face encounters between the customer and the bank are getting smaller and smaller. This can lead to a breakdown in the relationship.
