I was sitting the other day thinking about the good old days.
In the good old days, if something was big and challenging, banks would get together and create a co-operative to solve the problem. SWIFT, Visa and MasterCard were all bank created co-operatives. Admittedly, times have changed and now Visa and MasterCard are private entities, but originally they were created to solve problems that a single bank could not tackle like making global payments and processing billions of card transactions.
