It's not that they don't exist, it's that you don't have the POS being widespread enough to support it in a common way.

The Interac system in Canada is pretty much a given for any vendor that has a cash register. That automatically makes every single bank card into a direct debit card. You can choose to use it if you want of course, but it's default for all bank accounts, really.

This is still very wrong. US debit cards work with any credit card-accepting POS. If you can enter 16 digits and expiration date and get a charge, your debit card will deduct that amount from your checking account for you.
