Why can't I fill in the medical insurance card number on the small micro health appointment registration card?

The medical insurance card is used to pay medical expenses, not registration fees. According to the national policy, it cannot be used to pay the registration fee. Registration requires an outpatient card, and you can make an appointment in advance. Medical insurance card (hereinafter referred to as medical insurance card) is a special card for personal account of medical insurance. It takes personal identity card as the identification code, and stores and records detailed information such as personal identity card number, name, gender, expenditure and consumption of account funds. The medical insurance card is undertaken by the local designated agent bank, which is a multi-functional debit card of the bank.
