A client of mine asked if DT Register has integrated with DWOLLA. I have never heard of DWOLLA but checked them out and they are pretty interesting. They are cheaper than Visa & Mastercard and works similar to PayPal but not with all the fees. They make it easy to pay with your phone. Here is the link to their website -

I told my client not sure about the integration but i would pass it along. Seems pretty cutting edge.
