Oh sure, debit vs credit is largely a non-distinction here since debit cards are generally on the same network: Visa or less commonly MasterCard. So unless there are other business-related reasons to deny debit cards (currency conversion or cross-border regulations maybe?), they should be handled by the same processor as a credit card and usually for a much lower transaction fee too!

I’m US based and always use credit cards online (and pay them off every month of course) for the strong consumer protections they offer vs debit: $0 fraud liability, extended warranties, and rewards points/travel miles.

I’m curious about your experience here: have you ever encountered a scenario where you wanted to use your debit card, but the merchant only accepted credit cards?
