Before I started selling at the Farmer's market in Glen Ellen a few weeks ago, I checked into the latest ways to accept credit cards. I was looking for something that didn't have a big monthly fee but was secure. I had previously use ProPay but just wrote down the credit card information then entered it into my computer later when I got home.
But now I've found Square. Its a little square that you attach to the audio outlet in your mobile phone (I use an iphone). You then swipe the card and fill in the price info on your phone (plus tax if necessary). The person signs on the phone and then you have the choice of sending them a receipt by email or text.
If you want to start accepting credit cards (or want a better set up than you already have), you really should check it out. You can also use it to accept cash, so that it keeps all your transactions in one place. You just by pass the credit card swipe part and enter the cash details and send a receipt or not. When you accept cash, Square makes no charges. They then produce good spreadsheets of all transactions accessible either on the phone or on your computer.
And the bit that the customers like the best is that I bought a little Pogo stylus to sign on the phone (or else you can use a finger). It's lime green - of course - my favorite color!!!
The Square is quick and easy to sign up for; I received the Square in a couple of days; and it was easy to get started.
And it works wherever you can get a phone signal. Take a look at Square's website for more info. Let me know if you give it a go.
