1. Which state government introduced Aadhaar-based biometric verification for crop procurement at mandis in April 2026?
[A] Gujarat
[B] Haryana
[C] Maharashtra
[D] Odisha
Show Answer
Correct Answer: B [Haryana]
Notes:
The Haryana government introduced Aadhaar-based biometric verification for crop procurement at mandis. Farmers or authorised representatives must verify identity via biometric scans before selling produce. Crop arrivals are cross-checked with the ‘Meri Fasal-Mera Byora’ portal (farmer registration database for land and crop details). The e-Kharid app (digital procurement platform) records vehicle number and captures load photographs before issuing gate passes. The system aims to prevent fraud (illegal sale of crops from other states under fake identities).
2. Consider the following statements:
- Aadhaar metadata cannot be stored for more than three months.
- State cannot enter into any contract with private corporations for sharing of Aadhaar data.
- Aadhaar is mandatory for obtaining insurance products.
- Aadhaar is mandatory for getting benefits funded out of the Consolidated Fund of India.
Which of the statements given above is/are correct? (UPSC Prelims 2020)
[A] 1 and 4 only
[B] 2 and 4 only
[C] 3 only
[D] 1, 2 and 3 only
Show Answer
Correct Answer: B [2 and 4 only]
Notes:The correct answer is
[B] 2 and 4 only. This question pertains to the landmark Supreme Court judgement in the
K.S. Puttaswamy vs Union of India (2018) case regarding the constitutional validity of Aadhaar.
- Statement 1 (Incorrect): The Supreme Court struck down the provision that allowed Aadhaar metadata to be stored for five years. However, it ruled that such data cannot be stored for more than six months, not three months.
- Statement 2 (Correct): The Court struck down Section 57 of the Aadhaar Act, which allowed private entities or corporations to use Aadhaar for establishing identity. Consequently, the State cannot enter into contracts with private corporations to share Aadhaar data.
- Statement 3 (Incorrect): Based on the ruling, the IRDAI (Insurance Regulatory and Development Authority of India) clarified that Aadhaar is not mandatory for purchasing insurance policies. It is a voluntary document for KYC.
- Statement 4 (Correct): Section 7 of the Aadhaar Act was upheld. It states that Aadhaar is mandatory for availing subsidies, benefits, and services for which the expenditure is incurred from the Consolidated Fund of India.
The verdict balanced the right to privacy with the legitimate aim of the State to ensure targeted delivery of subsidies, while significantly limiting the scope of Aadhaar usage by private players.
3. Consider the following statements:
- Aadhaar card can be used as a proof of citizenship or domicile.
- Once issued, Aadhaar number cannot be deactivated or omitted by the Issuing Authority.
Which of the statements given above is/are correct? (UPSC Prelims 2018)
[A] 1 only
[B] 2 only
[C] Both 1 and 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: D [Neither 1 nor 2]
Notes:The correct answer is
[D] Neither 1 nor 2. This question clarifies the legal status and administrative control of the Aadhaar ecosystem under the Unique Identification Authority of India (UIDAI).
- Statement 1 (Incorrect): According to the Aadhaar Act, 2016, and various clarifications by the UIDAI and the Ministry of Electronics and Information Technology (MeitY), Aadhaar is a proof of identity and proof of address/residence, but it is not a proof of citizenship or domicile. The Supreme Court and various High Courts have reiterated that Aadhaar is only an authentication tool for residents who have stayed in India for 182 days or more in the preceding year.
- Statement 2 (Incorrect): The Issuing Authority (UIDAI) has the power to deactivate or omit an Aadhaar number. Under the Aadhaar (Enrolment and Update) Regulations, 2016, an Aadhaar can be deactivated if multiple Aadhaars are found for the same person, if there are discrepancies in the core biometric/demographic information, or if the holder is found to be ineligible at the time of enrollment.
The Aadhaar project was designed primarily to ensure the targeted delivery of subsidies and services (Direct Benefit Transfer) and to eliminate “ghost” beneficiaries from the system, rather than acting as a nationality document like a Passport or Voter ID.
4. Consider the following:
- The identity platform ‘Aadhaar’ provides open “Application Programming Interfaces (APIs)”. It can be integrated into any electronic device.
- Online authentication using iris is possible.
Which of the statements given above is/are correct? (UPSC Prelims 2018)
[A] 1 only
[B] 2 only
[C] Both 1 and 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: C [Both 1 and 2]
Notes:The correct answer is
[C] Both 1 and 2. The Aadhaar project, managed by the
Unique Identification Authority of India (UIDAI), is designed as a digital infrastructure layer for various service deliveries.
- Open APIs and Integration (Statement 1 – Correct): Aadhaar is built on an open architecture. It provides Application Programming Interfaces (APIs) that allow various government and private entities to integrate Aadhaar authentication into their own applications and electronic devices (like Point of Sale machines or micro-ATMs). This “plug-and-play” nature allows for seamless digital identity verification across different platforms.
- Iris Authentication (Statement 2 – Correct): Aadhaar uses multiple biometric identifiers for authentication, including fingerprints and iris scans. Online authentication using the iris is not only possible but is considered more accurate and less prone to wear-and-tear issues compared to fingerprints. Many specialized tablets and handheld devices are equipped with iris scanners specifically for Aadhaar-based verification.
Key Features of Aadhaar Authentication:
- Multi-modal Biometrics: It supports fingerprints, iris, and OTP (One-Time Password) based authentication.
- e-KYC: Allows for “Electronic Know Your Customer” verification, significantly reducing paperwork for opening bank accounts or getting mobile connections.
- Security: UIDAI uses encryption to ensure that biometric data is not shared with the requesting agency during the authentication process; they only receive a “Yes/No” response.
