Have most of y'all switched over to those new 'chip' interac cards yet? My bank sent me one in the mail a few weeks ago and I still haven't made the switch over yet. Curious about the pros and cons. I realize it's an inevitable switch, but wondering if I should hold off a bit until all stores, and places of merchandise etc have made the upgrade. So I guess my question is, have any of you ever run into any problems with trying to use a bank card with the chip?
