I hate them, it is so silly.
it takes forever and fails all the time, you just sit there and keep trying.
and it is a waste, because when credit card info is stolen it is hacked from the banks or say target’s headquarters and they steal 100,200,300 million cards at a time. so the chip in the card to protect your credit card is silly. not to mention it does zero for all the online transactions and recurring charges say for your cable that are a super big chunk of credit card use.
