It's awful how behind the times the US is when it comes to banking. 2 - 3 days to get money from one account to another is beyond embarrassing in the modern day. It took the US something like 15 years to get chip-and-pin.
Banks are still these monolithic entities that don't care to innovate or listen to customers because "what are you going to do, go to one of the other 4 monoliths that are all in cahoots with each other"
