The Unorganised Sector Workers Social Security Bill 2007 was introduced in the Rajya Sabha on Monday. It provides legislative backing to all the social security schemes. These include the ‘Aam Admi Bima Yojana’, National Old Age Pension Scheme and the Health Insurance Scheme. The health insurance scheme has been formulated for below poverty line (BPL) workers and will cover six crore families progressively in the next five years. A provision has been made for issuing smart card, carrying a unique identification number, to each of these families.
