> And an inline popup that I would never trust to enter my credit card details. Wasted first impression on me. Then you wouldn't trust any non-brand-name site that sells things via credit card charges (which makes you fall outside of the entire e-commerce consumer space). Stripe isn't for Amazon and eBay, it's for those thousands of other sites out there that accept credit cards. If you would shop there using an inline payment form, you would still shop there with the modal <div> payment form. Believe it or not, people trust and use these kinds of sites every day.
