The VN 2000 series bill acceptor is widely known as the best validator on the market. The VN-2521 is most commonly used in cold food vending machines. This unit is what's known as a "flashport" model, which means it can be upgraded using a simple hand held programmer for any new currency updates that come out. These validators have already been upgraded to the latest currency versions, including the 2008 $5 bill. The VN-2521 model comes with a "slim" or "flush" style bezel needed for installation of these validators in machines like the National 430 cold food.
