Free Credit Card Audio Swiper

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.


Thanks Ed, I didn’t realize the reader is free.

FYI, that little information includes your SSN, birthdate, and address, even if registering as a company (which also requires your business tax id) - all of which are required by U.S. regulation according to the sign-up form.
