Square is an app for your smartphone. A small swipe reader jacks in the side and you sign with your finger. For an additional charge you can manually input the numbers too. Paypal now offers it as well. Paypal is great in that the customer can use a card or any bank account and you can generate an invoice easily. It let's my customers maximize their reward points. Funds are immediately available on my paypal visa debit card or they are transferred to your bank account. Its how modern business is done. I love waking up on the 15th and having 150+ emails from paypal that say "you have money"!
