Just thought I'd let everyone know of yet another option for credit card processing via the Smart Phone. We tried Roam Pay this weekend after having issues with data connectivity for both Square and Intuit GoPayment. Roam Pay worked much better, has a lower discount rate but charges .25 per transaction. Overall, I think it will be slightly less expensive for us than either Square or Intuit and the major advantage is that if you are somewhere with spotty data connectvity (a problem we've had with our last 2 shows) you can use the store and forward option to upload your transactions later. This saves us from having to use a knuckle buster and keying in the transactions later. After using this application, compared to Square and Intuit GoPayment, I think this is going to be our best option.
