Is there a difference between upgrading social security cards and not upgrading them?

There is a big difference between the two.

The upgraded three-generation social security cards are safer, more powerful, more convenient, more durable and more standardized. The third generation social security card adopts the domestic SM4 cryptographic algorithm, which has a larger chip capacity, increases the biometric function and the card-using function of non-contact card reading, reduces the physical loss of the card, unifies the card face in the whole province, and adds a watermark with local characteristics to the personal information face. For users, the third-generation social security card only adds the function of non-contact transaction, which is the same as the second-generation social security card in terms of medical treatment, drug purchase and treatment collection. It does not need to be replaced and can continue to be used normally.
