AllThingsD reporter Lauren Goode spent some time shopping with both Pay with Square and PayPal's new mobile payment app. The two solutions are one of several up-and-coming mobile payment platforms competing for your virtual wallet.

Not surprisingly, she noted that the biggest hindrance to either solution is the lack of merchants who are willing to offer mobile payments. It's still too new of a technology to go mainstream, at least right now.
