1) They're expensive (merchants pay ~3% fees which makes items more expensive for us) 2) They're not safe-- anyone can read the numbers off your card and steal it. This also makes credit cards more expensive, bc the banks need to charge more in fees to cover fraudulent transactions 3) They incentivize us to spend money we don't have (and then pay fees on that money) 4) They're inefficient. Requires 4-5 different parties to pass money around. 5) Only works in one currency and in one country (without paying massive fees)

I'm working on a project using Ripple that would solve all this, but it would require people getting something that worked more like a debit card instead of their credit cards.

Would you use it?

Would love to hear feedback.
