Can the QR code of Hunan residents' electronic health card be used as an ID card?

I can't. According to the information of official website, the People's Government of Hunan Province, the electronic health card for residents in this province is mainly used to manage and improve people's health, comprehensively improve the health level, effectively control the incidence of diseases, implement life autonomy, and promote medical reform and health reform. If it is not marked, it can be used instead of an ID card, so its QR code cannot be used as an ID card.
