If you have a newer iPhone, it's been a pain to take payments from magstripe cards using a Square reader -- without a native headphone jack, you've had to plug in a dongle and hold it steady while you serve a customer. Isn't Square overdue for a more iPhone-friendly version? Thankfully, it's here. You now have the option of a magstripe reader with a Lightning connection instead of the usual 3.5mm plug. There's nothing new apart from the port compatibility, but the identical $10 price makes it an easy choice if you run an iPhone-centric shop.
