Smart cards for the benefit of workers of unorganised sector will be launched soon. This Unorganised Workers Identification Number (UWIN) smart card will be launched by PM Sri Narendra Modi. This was stated by Union Labour Minister Bandaru Dattatreya in Coimbatore on Friday. He said, of the total workforce in India, 93 per cent, nearly 40 crore, is in the unorganised sector and the UWIN card will benefit the workers in various fields such as construction. According to the minister, all the four social security schemes of the Centre -- Jan Dhan, Jan Suraksha, Jeevan Bima and Atal Pension Yojana -- will be covered under this card. He said, UWIN will be portable as a worker can avail EPF and ESI benefits even if he migrates to another city.
