We are VeriFone programming experts.

Our expertise encompasses all aspects of software architecture, design, development, testing, and ongoing maintenance for leading POS terminal platforms, including:

OTI's project success list is extremely impressive and includes development of scores of payment applications from scratch, as well as outsourced maintenance and enhancements for a variety of previously developed applications.

We provide advanced capabilities including EMV and chip card technologies, POS system integration, communication solutions including Ethernet, WiFi, GPRS, CDMA, and traditional land line dial. We also provide integrated solutions utilizing any standard peripheral device from PIN pads, card readers, check readers, and barcode scanners, to RFID devices. Quite simply, we understand payment processing inside and out.



We stand behind our work... because we CAN.

Because of OTI's broad and proven expertise across virtually all business lines employing a point of sale terminal, we can produce high-quality results quickly, and at very competitive prices.

At the core of our approach is a rapid application development methodology. In most cases we can deliver a prototype showing the core processing functionality within a week from project start. Many changes can be made on the spot. There's no guesswork, no surprises, and no need for expensive re-work down the road.

OTI has also developed a wide array of fully tested, high-quality software components that simplify and accelerate the application development process. The result is reduced development cycles and lower costs, while still ensuring exceptional quality.

OTI stands behind all of its work. We take away all of the headaches so you can focus on building your business.
