I picked up a Square Reader from my local Apple Store the other day, here is what you get in the box!
For those of you who don't know, Square is a mobile payment system that allows you to take credit card payments. Of course, Square takes a small portion of the funds to pay for the transaction but this is a great tool for entreprenurs looking to expand beyond cash business.
You can sign up for an account and get sent a free reader in the mail here. If you don't want to wait, you can just go up to your local apple store like me!
