Checks banknotes immediately and anywhere. With the Safescan 30 counterfeit detection pen, you know in just 2 seconds whether the tested banknote is genuine or counterfeit. Simply mark the note and observe: If the ink turns dark, then it is probably counterfeit money. Perfect for a quick and mobile check, for example at markets and events or in taxis and delivery vans. The special ink works on all surfaces. The Safescan 30's iodine-based ink reacts with the starch contained in any standard paper, but not with the official cotton or plastic-based banknote paper used by central banks around the world. It also helps to remove counterfeit money from circulation: the colourless ink fades on genuine banknotes, but leaves a permanent purple mark on suspected counterfeits. Direct authenticity check. Ideal for travelling. Suitable for testing all currencies. Checks the old and new CHF banknote series. Dimensions: 13.5 x 1.5 x 1 cm. Weight: 9 g.
