Banking in the US feels like it's stuck in the 90s. Heck, half the time, it's not even chip+PIN, it's chip+signature (which is a relativelyrecent change from carbon copy or swipe and signature).

I've never had a web shop use an API to deduct from my bank account - the closest thing is PayPal, which as far as I can tell is basically ACH under the covers, just though an intermediary. Pretty sure more Americans use their CC or debit card for online shopping.
