Suzhou Education E cartoon shows that the balance of the ride is insufficient, which may be due to the following reasons:

1. The bank card function is not enabled.

2. The medical insurance card and the bank account are two independent accounts, and the transfer cannot be transferred to the medical insurance account, so there is no money when it is used.

3. Bus recharge needs recharging, and bank card and bus card are also two independent accounts.

I suggest you consult relevant personnel for specific reasons.
