I've had problems with purchases not going through, and, most recently, transactions showing as "failed" but still posting to my bank account. I was told that the debit is only a hold and that the charges will be reversed on the next business day, but it's still troubling.
I don't like the chip cards because they're slower and, in my experience, less reliable than the magnetic stripe. I know they're supposed to be "more secure". Your thoughts?
