1. Nowadays, any larger hospital can accept credit cards, and Tongji Hospital can definitely do it too!

Credit cards can be used as long as they are not overdrawn. The credit card machines are the same everywhere! The card machine doesn't care whether it's a debit card or a credit card.

2. The medical insurance card can only be swiped if there is money in it. That is to say, if you or your employer pay money into the medical insurance card every month, you can swipe it. (In fact, it is exactly the same as a debit card. You deposit money first and then use it.)

Now the country has also provided medical insurance for college students. The medical insurance card for college students usually only has the card number, and no one is there to deposit it. It's money, so you can't use it in outpatient and emergency services or pharmacies outside the hospital. If a college student is hospitalized, he can go through the medical insurance procedures with his medical insurance card (card number) or medical insurance account, and finally go to the school to reimburse part of it.

3. When swiping the medical insurance card, it only checks whether the password is correct. It does not limit whether the card is used by the person (what if the card is sick and comatose at the time?), or whether it is used by the person (go to the People's Congress). When you buy cold medicine at the pharmacy, does it still monitor you and you can only take it by yourself? What if your mother or son happens to have a cold?)

But if you are hospitalized, you have to go through the medical insurance procedures for inpatient A, and you can only use A's own medical insurance account. When paying for hospitalization, you can use other person B's medical insurance card to pay for inpatient A.

In a word, the essence of a medical insurance card is a savings card.
