Explanation:
Detailed explanation-1: -A counterfeit banknote detection pen is a pen used to apply an iodine-based ink to banknotes in an attempt to determine their authenticity. The ink reacts with starch in wood-based paper to create a black or blue mark but the paper in a real bill contains no starch, so the pen mark remains unchanged.
Detailed explanation-2: -A money-checker pen with color-changing ink makes it easy to detect suspect bills at a glance. The specialty ink made with ingredients like iodine chemically reacts with paper, printing in one color for genuine currency and another for counterfeit bills.
