STONY BROOK, NY--(Marketwire - Oct 9, 2012) - Applied DNA Sciences, Inc. (OTCBB: APDN), (Twitter: @APDN), a provider of DNA-based anti-counterfeiting technology and product authentication solutions, announced today that 3SI Security Systems is expanding its use of APDN's SigNature® DNA evidence marking product into 3SI smoke and dye cash protection systems used across Europe. First orders, to the banking sector, are already being processed.

3SI Security Systems is a world leader in cash protection systems designed to recover stolen cash and high-value assets, apprehend criminals and deter crime.

The smoke and dye system, called Thinpac™, is already in use in over 130,000 locations worldwide, with great success at deterring crime. 3SI called the addition of SigNature DNA marking to the Thinpac "a unique and leading edge security feature which we are happy to be able to offer to our customers." The company points out that "SigNature-DNA-tagged items can be identified unequivocally with a marker unique to a specific Thinpac, and hence unique to a particular crime. Any item, cash or person that comes in contact with the smoke will be marked by the SigNature DNA."

Police forces across Europe are becoming more familiar with the use of unique SigNature DNA markers in cash-protection systems, placing them in a much better position to catch and convict criminals. SigNature DNA provides police with a welcome additional investigative tool, which often reduces the amount of time it takes the police to undertake such investigations.

James Hayward, Chairman and CEO of Applied DNA Sciences, said, "Our SigNature DNA product is now used in many countries across Europe and is increasingly popular with police. One of our best examples of how the police make excellent use of our DNA to catch criminals is in the United Kingdom where 48 criminals have already been convicted and jailed for over 242 years, providing a great deterrent that has helped to significantly reduce the number of Cash in Transit robberies."

SigNature DNA is used to protect approximately 26% of cash movements in the United Kingdom.

Protection of bank tellers adds to APDN's portfolio of cash protection products. 3SI already uses APDN SigNature DNA marks to protect nearly 5,000 ATMs, using a DNA liquid which is placed in ink tanks that are fitted inside individual ATM cassettes. The cassette activates when triggered, marking all the cash inside the ATM and the criminals.

David Stanks, CEO of 3SI Corporation noted, "We have proven that we can significantly extend the value of our solutions by including the SigNature DNA products. This is a logical continuation of our strategy to deter crime and protect people."
