online for years now here in the US.......the checkout only asks for the credit card/debit card number, exp date and sometimes the CVA number on the back.... and sometimes if it's a Visa or MC....sometimes that's not needed because the number itself id's that info. I can't understand why Canada wouldn't have the same setup at their banks. I think I've only written four checks this entire year......I use my debit card everywhere I go now for gas, groceries, retail stores, etc. and make payments on my utilities online with it as well.
In the UK bank debit cards are accepted for on-line transactions for anything, just like Credit Cards. It makes perfect sense, they access the provider for an authorization, if there's enough money in the account, it goes through.
I hate Credit Cards, besides my wife trashed my credit. Why shouldn't everybody be able to use a debit card on-line just as they do in (I believe) most European countries? It would just be so damned convenient.
Ah well. c'est la vie.
