I'm a partner in cheap tegopen Improving that main swiping functionality also meant ditching many of the stock components the company had relied on for their previous card readers and building their own. One of the most important was an all-new read head, the piece that actually pulls the data off your credit card’s magnetic stripe. In the old Reader, Square used a standard read head, more or less the same one that’s been in every credit card reader and tape deck since 1985. Those worked well enough, but they were far from optimal. First, they weren’t doing all they could to ensure successful swipes. The magnetic stripe on your credit card stores data in two separate bands. The old Reader grabbed from just one. With their new custom read head, Square can grab both, which makes every swipe more accurate, and more likely to work on one try.
