Answer 1

A payment system isn’t as simple as what you might think.

1) You need to market this system to potential card holders. No one would adopt a system that didn’t have much use.

2) You need to market this system to all VENDORS. Every restaurant, supermarket, retail store, department store etc basically has an individual contract with the payment system. (ELI5) A store cannot simply put up a “VISA accepted here” logo. They have to sign up with VISA and agree to pay the company a percentage of their revenue.

3) This is a global system. So this is likely hundreds of millions of card holders and millions of vendors. No small undertaking for any bank. Plus, if it is an in-house system, the bank has to either operate a branch in every country or make agreements with some local banks to facilitate the payment system in every country. Financial transactions are highly regulated industries – a company cannot simply take or make payments in a country without first setting up a company that is registered to work there and comply to local regulations.

Basically, a new payment system would require years to build up a presence and tens of billions of capital and resources. On top of that likely billions more every year to maintain it.
