Thank you for calling RBI to know more about MANI i.e. Mobile Aided Note Identifier App. The app can be downloaded for free from Android Play Store and iOS App Store. After installation, the mobile application does not require internet and works in offline mode. The app can be used by pointing the smartphone camera towards the currency note and the denomination is announced in Hindi or English and can be communicated through vibrations also. This mobile application however does not check or authenticate the genuineness of Indian Banknotes and hence user discretion is advised.
