The document proposes providing social security to workers in the informal sector through a smart card system. It notes that 93% of the workforce contributes to 50% of GDP but lacks social protections. The proposed solution is for all informal workers to receive a smart card containing their identity details and biometrics which would allow them access to subsidized services. Employers would be required to record card usage data to send to the government. Non-governmental organizations would help implement and oversee the system at the local level. Challenges to the solution include economic costs, corruption, lack of political will, social issues like illiteracy, and maintaining the system as workers' locations and jobs change.
