> You can also walk your argument back, which is what I'd do if I were in your shoes. Good point. I'm just leaving my argument where it is, since I've poignantly lost. The way you summarized it made something clear to me, though, so thank you for your response. I had a response typed up to the "we need to switch to $X" elsewhere in this thread, then discarded it and went back to work after writing a much smaller one. That's probably the best way forward from the whole mess, since it is indeed true that magstripe technology is outdated and insecure. It's amazing to me that with the prevalence of strong crypto we haven't come up with something better that has been mass-adopted. Until Joe's Gas-n-Snacks in Bimbleberry, Kansas accepts my new-fangled card, I won't consider the replacement mass-adopted. There's an interesting aside: Square hurts adoption of new-fangled payment technologies because it caters only to magstripes. However, I still disagree on mere principle with "it's already broken, so no need to do it right for ourselves". That's a dangerous path to take in itself.
