Answer:
Banks and companies do this mainly for their economic and labor benefit.
But something that cannot be forgotten is that with this they seek to verify the loyalty of their customers, that is, to check if only that bank you occupy or if you occupy another one.
Explanation:
This phenomenon is not only attributed to globalization -which brought with it the proliferation of brands and therefore direct competition- but also to the “awakening” of customers due to the need to receive personalized products / services.
For example, 96% of bankers believe that their clients trust them more than any other non-bank competitor, and only 70% of clients agree with this statement. An even smaller proportion - 67% of customers - trust their primary bank compared to other banking competitors. Customer trust is being overestimated by surveyed banking executives.
