Ask HN: Are card payment fees so high outside the US?
I was surprised to learn that US merchants pay a baseline of 2.8% interchange + markup on debit card transactions, where the merchant accepts all risk if there&#x27;s a chargeback.<p>Is this the case in other countries? My friend is Danish and he says most use MobilePay—which seems to charge per transaction rather than as a % of value (it&#x27;s hard to tell).
