That's true, I am not too familiar with the finance system, how come a debit card needs a middle man such as VISA? They help with the transaction between two banks?





The situation is that there is a network called Visa Debit that some banks use for their network for debit transactions. It may seem new, but it evidently dates back as far as 1982.

I'm in Canada. With one exception, no bank client card I have had (which were all usable for debit) had any Visa logo on it. That includes current ones.

The exception is one TD client card.

The situation is explained here:

TD is one of the banks that offer Visa Debit. This TD client card is also Interac-branded, so I'm guessing that the card will use the Interac network for domestic transactions, and in that case its Visa Debit personality does not come into play.

Those are not the only two networks for debit/ATM in Canada. There is also "The Exchange":

(used by a lot of smaller banks and credit unions).

The Canadian Credit Union Association also runs an ATM network called AccuLink.

It's important to know which network your card uses if you want "ding free" transactions. E.g a "The Exchange" card can be used at an "Interac" ATM, but there will be a fee.
