The government has proposed radical changes in the Aadhaar Act giving greater power to Aadhaar number holders for use of their Aadhaar numbers only through informed consent and also prevent any denial of services if an Aadhaar number holder is unable or unwilling to furnish it to any service provider. It has also proposed an option for children to completely opt out of Aadhaar number after attaining the age of 18 years. Section 4 of Aadhaar and Other Laws Amendment Bill, 2018, which has been introduced in the Lok Sabha on Wednesday provides the option to completely opt out of Aadhaar number after becoming adult. In the existing law - Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016, there was no provision for any person, including children, to opt out of Aadhaar ecosystem, once their names have been enrolled.
