I assume the question is for me.
Google Wallet, or others like it—Amazon Payments, or PayPal, and there is a slew of them—not only use credit cards. In the U.S., the fact that your debit card is VISA or MasterCard branded allows you to use debit cards online. They also allow you to do ACH, where you give the provider your bank routing numbers and they can draw money from your bank account. So by virtue of being part of Google, PayPal, Amazon, or others, you are now able to access money directly from your bank account.
Actually this space, the whole peer-to-peer and wallet space in the U.S., is heating up quite a bit. As it comes to Canada, it will increase adoption, of course, because if you trust Google and you have everything Google, Amazon, PayPal, or whatever, you have your digital identity in a way tied to your credit cards or debit cards online and you can transact more readily. It does, in a way, provide some layer of safety because those programs have some buyer protection as well, on top of what your standard credit card or debit card gives you.
The trick for Canada is easily tying your debit card and access to your bank to your wallet. It's not easy because you don't have a network branded debit card.
