News About Aadhar

  • Social Media Accounts could be linked with Aadhaar – Talks ongoing

    The Ministry of Electronics and IT has gotten in touch with the Unique Identification Authority of India, asking if it is plausible to link the 12-digit identification number with social media accounts. The move is being considered following the Supreme Court getting in touch with the central government regarding the matter. A senior government official said that the Ministry of Electronics and IT had asked the UIDAI’s on linking the social media accounts to Aadhaar numbers.

    According to the official, who remains anonymous, although the Ministry hasn’t formulated a final opinion on the same as yet, a linkage such as this could be very difficult considering the fact that the Aadhaar number can be linked only to government subsidies and government welfare schemes that are funded out of the country’s consolidated fund. In 2018, the Supreme Court of India had restricted the mandatory use of Aadhaar only to PAN, for central government subsidies that are funded from the country’s consolidated fund, and for income tax returns. These changes were later added in the Aadhaar and Other Laws (Amendment) Bill, 2019. The bill was amended recently to allow banking and telecom companies to use Aadhaar for the collection of KYC details, albeit with the consent of customers.

    The official went on to add that even if social media accounts are linked to Aadhaar, there would be no purpose to it. He gave an example, saying that if there is a crime, the government will need the individual’s mobile number and other details that are linked with the person’s Aadhaar, and that goes against the rules of the Aadhaar Act.

  • Crop loans to be distributed this year

    The Chief Minister, Ashok Gehlot, mentioned that the government would support the farmers by providing crop loans of over Rs.16,000 crore. By doing this, farmers will be encouraged to establish their own agriculture enterprise and won't be forced to sell produce at a lower price. He further went on to say that the Indian government would help them set up food processing units.

    The process of distributing these loans would now be simple as it is going to be Aadhaar based. This means that farmers can simply withdraw the money from their ATM cards, removing several discrepancies. Over 20 lakh farmers have already applied for the Aadhaar based waiver scheme, and 10 lakh additional farmers would be added to the loan distribution process.

  • Aadhaar Card mandatory for sale of subsidised fertiliser

    The government has rolled out a point of sales (PoS) software as part of their DBT 2.0 fertiliser subsidy. The long-term objective of this plan is to ensure that the subsidy goes straight to the farmer and not the company as is currently the practice.

    Unlike most schemes, however, the subsidy to the fertiliser companies is being transferred on the basis of actual sales made by them.

    In fact, the government has also made the Aadhaar card mandatory for sale of fertilisers in order to place a check on any sort of diversion or duplication.

    These PoS machines have been installed in 2.24 lakh retail fertiliser shops in the country.
