Why is there a social security card in the household registration?

The financial social security card was sent to the account location because:

On 20 1 1 year, the People's Bank of Ministry of Human Resources and Social Security and China jointly issued the Notice on Loading Financial Functions on Social Security Cards, and decided to load financial functions on social security cards. Since 20 1 1, various provinces and cities have successively issued social security cards loaded with financial functions. At present, out of 2 1 prefecture-level cities in Guangdong province, 19 have issued financial social security cards. According to the unified arrangement of the state, the social security department can collect, update and improve the information of the insured in the process of changing the card, so as to make preparations for realizing the goal of "one card is multi-purpose and universal" proposed by the state for social security cards, and facilitate the people to enjoy social security benefits to a greater extent.
