<prompt> Human: I have an AMEX card with a chip. Supposed to be this new great security feature. It never comes into play in my daily life except for doing a self checkout at wal-mart. At that time, Im asked to slide the card into the bottom of the box where you swipe your card, which I do.Each time I do it though, it usually hangs for five minutes or longer, I end up calling over someone who works there, and they end up just checking me out from their register. This has happened at multiple wal-marts, not just one location.Anyone else experiencing this problem with these chipped credit cards? Either specifically at Wal-Mart or AMEX cards? How are these chipped credit cards supposed to be better if they dont work properly? Im all for more security, but I cant just stand around at the checkout counter for minutes upon minutes when seemingly nothing is happening.  <response>: Growing pains exist with any advance in technology.Once the bugs are worked out itll be awesome.Source: Been a ChipPIN user for years now. Its awesome.
