Data Guard Systems Lets Cellular Retailers and Wholesalers Market Prepaid, PIN-Based Minutes Via New CellularManager® Prepaid OnDemand™

New Offering Promises Up to 40% Increase in Profit Via Company's Preferred Rates

CAMBRIDGE, MA, DECEMBER 12, 2006 — Data Guard Systems, Inc., a developer and marketer of online business management software, today announced the debut of CellularManager® Prepaid OnDemand™, an enhancement to the company's CellularManager® point-of-sale and enterprise management software platform. CellularManager Prepaid OnDemand allows cellular retailers, wholesalers, and master agents to sell prepaid cellular minutes in real time over the Internet via PINs that are made available to the end user.

With the maturation of the cellular industry and the shrinking of new account activations, cellular retailers are looking for new ways to generate revenues. Prepaid wireless is currently the fastest growing sector of the cellular marketplace, with 15% of the overall market, according to statistics from The Yankee Group. "Unbanked" users, youth, and budget-conscious or infrequent users are the groups who most often use prepaid.

Through the use of Personal Identification Numbers (PINs), CellularManager Prepaid OnDemand quickly and cost-effectively serves the prepaid wireless market. It also allows retailers, wholesalers, and master agents to eliminate stagnant plastic card inventory, minimize shrink and fraud, and gain added profit via the most aggressive wholesale prepaid rates on the market today.

"CellularManager Prepaid OnDemand is a natural evolution of the prepaid market," said Timothy Maliyil, President of Data Guard Systems. "Beyond the obvious savings brought about by eliminating prepaid card inventories, this new web-based concept is the lowest-cost method yet to market prepaid minutes. Even more, Data Guard Systems has leveraged its substantial customer base to obtain the most aggressive rates for our clientele. Our clients will see, on average, a 40% increase in profit per PIN from CellularManager Prepaid OnDemand."

Data Guard Systems' CellularManager Prepaid OnDemand can be fully integrated into the company's CellularManager cellular point-of-sale software. To learn more, visit www.dataguardsystems.com.
