Magnetic detection

Magnetic detection is a method of banknote authentication that checks for the presence of magnetic elements. These elements are part of the security systems of modern currencies and are invisible to the ordinary eye. They are mainly a special printing ink, known as "magnetic ink", which contains metal particles. A counterfeit detector equipped with magnetic detection has a sensor in it that detects whether this ink is present in predetermined places on a banknote as it passes through it. For some currencies, such as the US dollar, it also checks for the presence of a magnetic security strip that is embedded in the paper. If the sensor does not detect these magnetic features in the correct places, the machine will evaluate the note as suspicious. This technology is used by currencies such as the euro, the US dollar and the Czech koruna to protect their banknotes.
