Applied DNA Sciences, Inc. Signs Contract for Its DNA Security Access Systems

LOS ANGELES--()--Dec. 7, 2004--ADNAS (OTCBB:APDN) has received a contract from an unnamed Washington state government agency. The purchase order includes the delivery and installation of multiple DNA security access systems (DNASAS) as part of the agency's plan to upgrade facilities and perimeter security, as well as improve data and information systems security.

The DNASAS operates in much the same way as traditional access control/card reader systems, but that is where the similarity ends. The DNASAS uses a proprietary method to integrate stabilized botanical DNA within the actual microchip mounted on the surface of the access card. When the card is inserted into the reader, it will only operate or permit an operation if the DNA signature on the cards' microchip exactly matches a specific DNA model, in that specific reader.

The DNASAS reader technology is unique in the security industry and recently won the Best of Show and the Product Achievement Award for access control, at the National Summit on Security, sponsored by the Security Industry Association (SIA), whose membership includes market leaders like HID and ADT.

One of the most obvious security benefits of the DNASAS is that it shares very little in the way of core components with other security access systems on the market today. There are no other sources for key components other than Applied DNA Sciences, Inc. One of the main criticisms within the security industry has been that access control cards are now common and readily available to anyone to order, reorder or to replace a "lost" card. The integrity of the DNASAS product is also fortified by the integration of fingerprint recognition, providing absolute authentication between the cardholder, their fingerprint and a unique DNA code.
