> Here (NL) contactless payments works with every debit card, physical or stored Apple Google/Pay, in every store

That's how it works in the US as well. You might be conflating Apple Pay with Apple Wallet, which stores your credit cards for tap-to-pay. Most people in the US use Apple Wallet/Google Wallet to digitally store their credit/debit cards, and use those cards to pay at the store by tapping the POS terminal.

For example, I use Apple Wallet for nearly every transaction, but I never use Apple Pay/Apple Card as the payment method.
