I live in the US, and they released a Bluetooth chip card reader to solve the lack of headphone jack problem. Gift cards don't have a chip though. Which means it will still need to be ran through the headphone jack reader. Also a small percentage of credit and debit cards out there still don't have a chip- though I do notice that a majority of my customers do use the new chip card reader because more and more cards have chips. What do you think Square is going to do? I doubt a lightning adapter will work with square.
