Mobile phone electromagnetic waves interfere with the banknote validator "blinding" it

It is reported that a kind of mobile phone has emerged. The special electromagnetic wave emitted by this kind of mobile phone can interfere with the banknote detector, causing it to "go blind" and fail to identify counterfeit money. The other day, a merchant in Fuzhou city of our province (Jiangxi Province) received counterfeit money as a result. IT Tang would like to remind all Internet users to be careful.

On the 11th, an event occurred in which a banknote detector in a sundries shop on Daguong East Road in the urban area of Fuzhou city suddenly "malfunctioned" and did not detect counterfeit money. A man used counterfeit money to buy cigarettes and the banknote detector didn't detect the counterfeit money. The police found through experiments that within a distance of 25~30 centimeters, the electromagnetic wave from a mobile phone might interfere with the banknote detector so that it would not emit an alarm sound when detecting counterfeit money. Currently, the vast majority of banknote detectors on the market will malfunction under the interference of mobile phone electromagnetic waves.
