Google Wallet

From the FAQ:<p>&#62; Can I use Google Wallet with my phone?<p>&#62; Google Wallet with tap and pay will be compatible with Nexus S 4G by Google, available on Sprint®.<p>Now I know they have to start somewhere, but I have doubts about their ability to gain traction when they have compatibility with one device on one carrier at launch. They'd better ramp up quickly if they don't want this to be another Wave.

Why does it matter what carrier my Nexus S is on? If all the Nexus S models have NFC capabilities, what difference does it make that mine is the GSM model on T-Mobile or a regional GSM/CDMA carrier vs a CDMA model on Sprint?<p>Edit: nvm, didn't see the other discussion: <a href="http://news.ycombinator.com/item?id=2588380" rel="nofollow">http://news.ycombinator.com/item?id=2588380</a>

I'm more excited for the Google virtual prepaid card. For some reason, a lot of credit cards don't offer one time use credit card numbers for online spending. I know Citi does and at one time paypal did

I find it amusing that the logo looks like wave's. Actually, I'm pretty sure I've seen that exact logo design somewhere else (not Google related, however).

So the idea is this is more than credit cards, it is about using NFC to replace keys, boarding passes, and whatever else you can think of. Not so clear on the monetization for google. Well after my first gen iphone broke, i still don't have a smart phone. Is this worth $30 a month yet? No, not to me.

How can the google wallet site not use sprites for the navigation images? <a href="http://cl.ly/77E8" rel="nofollow">http://cl.ly/77E8</a><p>Oh, and the links don't work when you click on "How it works" <a href="http://cl.ly/76Vv" rel="nofollow">http://cl.ly/76Vv</a><p>TIL I could work for google.

Am I missing something? Why can't they just produce a Micro-SD card that can run in card emulation mode? Wouldn't that allow a lot of people to use this without new phones?

So, could this work between two phones? That would be interesting: Paypal meets Square (and possibly disrupts both).
