Thanks to the new Costco Amex, I have my first chip credit card. Used it at Target last week and it was a minimum of 30 seconds while I waited for the machine to tell me I could remove my card AND I was told not to insert it until the cashier was done ringing things up. Used to be able to swipe my card while the cashier was ringing up my things and it was back in my purse before she was done. I’d say this transaction was at least a minute, maybe two, longer than it would have been before. So, I agree that I hope it all becomes more efficient as we (merchants and customers) transition. (I’m also not complaining about a 2 minute delay – just observing.)
