Greetings hackers.
Square Up is giving away their credit card swipers on their site:
It connects through the audio port of a smartphone and allows you to
take credit card payments with their app. They only ask for a little
information and there's no commitment. I figured it is something that
would be useful to have around (and maybe hack a little) and thought
others might as well given the maker movement and having the ability
to accept credit cards where ever you are.
