2005 ETA Annual Meeting & Expo, LAS VEGAS, NV, March 16, 2005 –Authorize.Net Corp., a service of Lightbridge Inc. (NASDAQ:LTBG), today announced that it has completed an initial beta release of its new Virtual Point of Sale (VPOS) product. VPOS is designed to provide a secure, easy-to-implement, easy-to-use solution for “brick and mortar” retail merchants using the Authorize.Net Payment Gateway.

To use VPOS, retail merchants simply need an Authorize.Net Card Present (CP) account, a CP merchant account, a computer running Microsoft(R) Windows(R) with Internet Explorer 6 and a supported credit card reader by MagTek. Distributed as a private label solution through Authorize.Net`s extensive network of reseller partners, VPOS will initially be offered through resellers capable of providing tier-one (first call) support.

“Authorize.Net is committed to being the industry`s leading payment gateway for all merchant Internet Protocol (IP) transaction processing needs,” stated Roy Banks, Authorize.Net president. “Just as our Virtual Terminal allows e-commerce and mail or telephone order merchants to easily submit transactions manually via our Merchant Interface, VPOS allows merchants in retail locations to take advantage of the speed, reliability, and cost benefits of submitting credit card transactions via Authorize.Net`s Internet Protocol Payment Gateway.”

“We`ve had a lot of merchant demand for a virtual POS terminal,” added Matt Ward-Steinman, Authorize.Net director of product management. “We are pleased to answer that demand by introducing a product that is both cost-effective and secure. For any retail merchant, the incremental costs for the MagTek reader are considerably less than the cost of a dedicated POS hardware terminal. Additionally, we have built a number of important security enhancements into the solution that uniquely positions VPOS apart from competing solutions that lack security features.”

Authorize.Net will be demonstrating the VPOS solution in their booth (#810) at the Electronic Transactions Association (ETA) Annual Meeting and Expo, March 15-17 at the Mirage Hotel, Las Vegas.
