Business Description
The company provides an open architecture hardware and software system that can serve as a platform for the delivery of multiple products and services to the wireless telecommunications industry. The genesis for the platform is PhonePrint, a system that has proven highly effective in reducing cloning fraud. The PhonePrint system has prevented over 100 million fraudulent call attempts and some customers have reported up to 90% reduction in cloning fraud losses after deploying PhonePrint. In addition to providing cloning fraud prevention, the company's platform is designed to support a broad range of products and services for the wireless telecommunications industry, including churn reduction and phone location products. The company believes that new products can be integrated with certain hardware and software designs and components of its open, scaleable platform, which can provide a number of benefits to wireless telecommunications carriers, including accelerated development and deployment, reduced costs, efficient use of cell site space and improved customer service.

Use of Proceeds
