I'd really like the ability to add all my shopping cards, membership cards, and whatever else that constitutes 98% of my wallet. Replacing two credit cards/bank cards isn't that compelling. And then really, while I'm dreaming....I just want my phone or an app on my phone to deal with paying because carrying around a card just feels so 2000s. This is a slick implementation, though. I'm also more worried about actual merchants refusing to take something like this.
