The Cassida 3300 is a fully automatic counterfeit detector that adds a sophisticated layer of protection to your cash operations. Currency counters with UV detection capability check only for UV security features, which have been counterfeited. The Cassida 3300 CAD checks for infrared security marks. These marks are the most advanced security feature of Canadian bills, and are not known to have been counterfeited. This IR detection, combined with the 3300''s optical image analysis and magnetic ink and metal detection, create a formidable barrier to fraud. Compatible with all Canadian paper notes and $20, $50, and $100 polymer bills, the Cassida 3300 is built with the most reliable detection technology available in the industry and can detect even the most sophisticated counterfeits And because of Cassida''s work with Canada''s central financial institution, an upgrade service will be available to ensure full compatibility with the new $5 and $10 notes, expected to be released in 2013 (upgrade available one month prior to the release of the new bills).
