> How widespread is this, quantitively? Anecdotelly, I work in online retail, fraud is always a problem and we turn away business to avoid iff'y situations because of it and get attacked by streaks of stolen cards from time to time. Fraud is a real problem for merchants; you can't fight a charge back, you're out the money and the good and you just have to eat it and say thank you while getting killed on credit card fees. Credit cards suck for merchants, we accept them because we must, everyone prefers cash.
