The document proposes a system using NFC chips embedded in Indian currency to help identify black money and counterfeit currency. The NFC chips would contain identifying information like the currency value, tag number, and expiration date. The system uses four methods: 1) Money counting devices with NFC readers for offices/shops, 2) NFC readers that attach to Android phones for small businesses, 3) QR codes containing account details for vendors who can't afford readers, and 4) cashless transactions using cards. Together these allow the Reserve Bank of India to track all transactions and identify unreported income. The goal is to effectively eliminate black money and fake currency.
