I am already setup with Paypal for online purchases, but now I have the ability to accept credit cards and NO MORE MONTHLY FEES!
Once I signed up with Square I received one of these small swiper plug-ins for my iphone. After swiping the card, the dollar amount and description is entered on the phone, I can even include a photo of the purchase! A receipt is then sent in the form of an email (or text message) which includes the dollar amount, description, customer's signature, and my business information.
Please let me know if any of you have heard of Square or similar applications, I am still curious and open to learning about various options that do not carry a monthly service fee.
