Ira ChandlerCurbstone's founder, Ira Chandler, wrote the first commercial credit card processing software for the IBM AS/400 in 1993 at his previous company, ROI Corporation.  When that company was sold to Verifone, Curbstone Corporation was incorporated in 2002 to maintain focus on the IBM Midrange market.  Today, a staff of PCI QIR-certified integration specialists work to integrate expeditiously and securely, and ensure our merchants pass the highest quality transactions to qualify for the best rates.

Curbstone has grown to handle ~$2.4 Billion in transactions annually, and is a Gold Partner of TSYS, one of the largest Acquiring Banks in the US.  Curbstone is also a Premier Partner of Chase/Paymentech.  The millions of transactions processed through Curbstone Technology include Phone Orders, e-commerce on any platform, and Retail, using EMV terminals.
