The Indian government has mandated the linking of the PAN (Permanent Account Number) Card and Aadhaar Card. The PAN Card is used for financial transactions and tax purposes, while the Aadhaar Card provides unique biometric identification. Linking these cards reduces the chance of duplicate or fake PAN cards, simplifies tax filing, and aids in curbing tax evasion. Linking can be done online or offline, and failure to comply can result in penalties and difficulties with certain transactions. Despite concerns about data privacy, the benefits emphasize transparency, accountability, and efficiency.
