USA ePay has come out with a hardware attachment that will allow automatic credit card processing through the Blackberry. The device works on Blackberry handhelds that have OS 4.0 installed. The program has already been tested and deployed. The first major customer is Prime Time Shuttles, which has been testing the device in its LA location and will soon launch nation-wide.
I can see it now, pizza delivery men and woman racing to the stores to buy a Blackberry.
