Uidai Aadhar Card
In short
The Aadhaar card is a unique 12-digit identity number issued by the Unique Identification Authority of India (UIDAI) to residents of India.
In plain words
It uses your fingerprints and eye scans to prove who you are. This digital ID helps people access government services and bank accounts without needing many different papers.
A simple example
A person uses their Aadhaar number at a local post office to collect a government subsidy directly into their bank account.
Why it matters
It reduces identity fraud and ensures that welfare benefits reach the correct people. It acts as a single, reliable proof of identity across the entire country.
Easy to mix up
Do not confuse it with a PAN card, which is used specifically for tax and financial purposes in India.
