Until now processing credit cards was a pain, having to write down the number, experation date and CVC code number. Then you had to remember to manually enter it at teh end of the day or you wouldn't get paid. Doing it this way cost more than a regular transaction since the banks did not consider it a secure method and it was less than professional.
Having seen t.v. ads for something called squareup, a device for accepting credt cards using a smart phone, I thought I would give itg a try. The device itself is free! I ordered one online and it arrived in the mail two days later. a text message is sent to your phone and opeing it laods the necessary software and you're ready. Just swipe the card, enter the amount and send. Funds are sent to your bank each night and they only charge 2.75% for the transaction. I pay that much with my merchant account plus a monthly service fee.
Accepting credit cards opens your business to more potential customers, advertising the credit card logos in your ads lends credibility. The square-up makes it all easy and affordable.
