Continue reading as we break down every detail so you can understand not just the basics, but also the small but crucial aspects of BHIM Aadhaar Pay.

What Is BHIM Aadhaar Pay?

BHIM Aadhaar Pay is the merchant interface of the BHIM app, launched by the Government of India and NPCI on Ambedkar Jayanti, April 14, 2017, with the goal of enabling digital payments through Aadhaar-based biometric authentication, especially for those without cards or smartphones.

Why BHIM Aadhaar Pay Matters

• It enables inclusive digital payments—no need for debit/credit cards, OTPs, or internet on the customer’s end.
• At launch, 27 major banks and over 700,000 merchants were enabled to begin accepting such payments.
• Built on NPCI’s Aadhaar Enabled Payment System (AePS), it leverages secure, interoperable biometric authentication between UIDAI, NPCI, and banks.

How Does BHIM Aadhaar Pay Work?

Here’s the step-by-step journey of a transaction:

Step 1: Merchant Setup

• Merchant downloads and installs the BHIM Aadhaar Pay app on a smartphone or tablet.
• A UIDAI-certified biometric scanner (fingerprint reader) is connected to the device.
• Merchant links their Aadhaar number and bank account to the app.
• A secure merchant PIN is set to log in.

Step 2: Customer Initiation

• The customer approaches the merchant and provides their Aadhaar number (or scans the Aadhaar QR if available).
• The customer selects their Aadhaar-linked bank from the app’s drop-down list.

Step 3: Transaction Entry

• The merchant enters the transaction amount in the app.
• The customer’s Aadhaar number is validated.

Step 4: Biometric Authentication

• The customer places their fingerprint on the biometric scanner.
• The fingerprint is verified in real-time by UIDAI.

Step 5: Back-End Processing

• NPCI routes the transaction through the Aadhaar Enabled Payment System (AePS).
• The customer’s bank account is debited, and the merchant’s bank account is credited instantly.

Step 6: Payment Confirmation

• Both customer and merchant receive an SMS confirmation (if their numbers are registered with their respective banks).
• The merchant can now safely hand over the goods or services.

Who Needs the BHIM Aadhaar Pay App?
