As the subject says, I am atempting to use the intuit GoPayment app to process credit card/other forms of payment. It looks quite accessible, not all items are labeled properly but with some trial and error, it's easy to figure out what is what. I signed up for a free account through the website and chose to receive a free card reader. Unfortunately after it was shipped, I realized that it would probably be connected through the headphone jack, since most card readers send audio signals. In looking at the website though, I did notice what might be one model that uses bluetooth. I have not received the reader yet but if it is the headphone model, I will definitely contact them to see about purchasing any other models they may offer. Has anyone else had success in using any of the above?
