is the fundamental act of a card swipe broken ? On on hand, I can clearly see the value of Square... and on the other hand, I can also see the value of business models like LevelUp (that commoditize mobile payments and leverage marketing budgets).

But is a disruption of mobile wallets vs credit cards even possible ? Why would a 19-year old college student prefer it ... or why would a 30 year old professional switch to it over credit cards ?
