Square's New Reader

MacRumors: Square Debuts New Card Reader Developed by Former Apple Lightning Connector Designer

To develop the thinner card reader for Square, Dorogusker was forced to move away from stock components and develop proprietary hardware such as a new custom read head that is able to read two bands of data from the magnetic stripes on credit cards, resulting in greater swipe accuracy. 

Dorogusker and his team concentrated on improving the "feel" of swiping, incorporating additional tension in a spring that attaches to the read head for a more satisfying credit card swiping experience.

Wonderful to see such a great company make such an explicit effort toward the details of using their product.

Not There Yet

I largely agree here. The smartwatch thing just isn't there yet. I like my Pebble (I was an early Kickstarter backer) but it isn't something I can't live without. It is too thick, iOS is admittedly limited with these types of devices, and the 3rd party app support isn't what I hoped it would be.  There is hope for the market, but it is going to be a while before this takes off.
