Amateur engineer develops a cellphone-based solution for detecting fake currency

29 Dec

Approximately Rs 1,69,000 crores is the estimated amount of  counterfeit currency which is unsuspectingly circulating in the Indian financial system. Neha N of Vidya Vikas Institute of Engineering & Technology, Mysore designed a “cellphone based intelligent counterfeit teller” and her proposed scheme won a competition organised by Schneider Electric India.

Schneider Electric India, a global specialist in energy management, organized a unique contest called ‘Innovation Challenge’ (IC) for the undergraduate engineering minds of India to bring up innovative solutions for efficient utilisation of energy. The winning idea is an innovative solution to detect fake currency through mobile phones.

The counterfeit teller works using the UV-visible and infrared sources, low power sensor chip and the cellphone processor for detecting fake currency. Consequently, the cellphone acts as a sensor when put in the detection mode. Similar concepts of image processing, signal processing and pattern recognition are used for checking the authenticity of currency as per the RBI standards. If the device detects fake currency, the display of the cellphone screen will show a warning along with an audible warning alert.


Moreover, since the proposed scheme works on phone battery and uses low power consumption techniques for processing, it consumes approximately 45 percent lower energy when compared with the currently available stand alone counterfeit detection units which mostly work on AC supply.
