> Canadian PoS terminals often support US debit cards. Unless something changed in the past few years, this is not the case. US debit cards are accepted through Visa or Mastercard's payment network which doesn't require a PIN (this is what it means when you process as credit in the US). Those transactions do not use the debit payment network. https://en.wikipedia.org/wiki/Interlink_(interbank_network) https://en.wikipedia.org/wiki/Interlink_(interbank_network). EDIT: I will add that while POS systems don't have a way to do this up there, ATM's with their notoriously high fees do support cash access through a US debit card.
