The Safescan 155-S uses the latest counterfeit detection technology to scrutinize seven advanced security features built into today’s currencies: infrared ink, magnetic ink, metallic thread, color, size, thickness and watermark. This technology is so reliable it even detects double notes and half notes. In just half a second, you’ll know with 100% certainty whether the banknote in your hand is genuine or counterfeit-and your customer will know, too, eliminating unnecessary discussion.
