Very cool looking, would love to use it, but there's two main problems: 1. No free trial, dropping $300 on a javascript plugin that I don't even know works yet is a lot of money. 2. I don't know if the value it offers is THAT much different from other credit card validation tools. If I'm making $50/hr freelancing, that's 6 hours of my time and I could easily customise some other alternative to fit my needs in that time.
