Similarly in the NL if I want to send someone money to anyone in the EuroZone I open my bank app type in their IBAN type in the amount of money and hit send. Done.
Back in 2017 when I lived in the US this just wasn't possible. If I wanted to send money to someone I had to use Paypal, TransferWise (or similar), Venmo, etc. Some banks had direct access to ACH but far from all, then if they do support it it takes two days to arrive. Some banks allowed easy instant payments between accounts within the same bank. Much of my family purposefully keep an account with a small west coast credit union to facilitate moving money amongst ourselves.
Maybe things have gotten massively better in the US in the last 3+ years, but it was light years behind the UK and NL. In terms of speed, ease of use, and adoption.
