> I suspect abandonment rate is rather low. I'd say it depends on the situation. If you're shopping for something specific, say for a new hard drive or monitor or something, chances are you've been looking around for awhile and once you're in the checkout process, you've made up your mind to commit to that product. A few extra fields for payment data probably won't deter you. But on the opposite side of the spectrum, if someone is going to impulse buy, each field you force them to fill out gives them a few more seconds to decide "Eh, I don't really need this..." and abandon. In those cases, you want payments as frictionless as possible. I know I've done some impulse buys a few times after being drawn in via an email campaign or something--and subsequently decided to just forget about making the purchase.
