You guys use the debit card linked to your primary bank account??? There's been virtual cards for online shopping for 10+ years now. They're meant to be linked to an empty or low amount bank account. Now with Revolut you can schedule auto top-up to keep this low amount up to date.
Not to mention the per-purchase (online/in-person) limits, mandatory PIN entry, and daily maximums...
We don't use any cards for online shopping, what do you mean? In most European countries online shopping uses a payment API that takes you to your bank's payment portal where you can review the transaction amount before confirming. It's no longer the 20th century, we're not handing out any card details to online merchants.
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.
Of course all online merchants in Europe take card payment. Some of them also offer payment by bank payment portals, such as you've described. These have zero benefits for the customer.
We have virtual cards as well, maybe used it once. But we also have a lot less fraud and typically require 2fa for online purchases and chip+pin every x purchases.
