I just received my first ever credit card reader in the mail! I am really excited to have this device added to my business. I think this is going to be a big help to me when it comes to shows. I had been thinking about getting one for a while but was hesitant due to expense questions I had and wanting to really be sure this was a safe and secure method of payment. I wanted it to be worth the endeavor and I think this totally is! I had compared all the different options (I think) that are out there for being able to take credit payments through a smart phone. PayPal Here was the best option for me, especially since I have had a business account set up with them already for my Etsy shop. I tried it out with my own card and it could not be more simple to operate! Plus, I love that you sign with your finger! After the sale goes through I can give the customer the option to receive a receipt via e-mail, text, or not at all. I am bringing this with me for my spring show in Maryland this April, but I plan to use it with the iPad rather than the phone.
