Relative card consumption limit
The relative card itself has no limit, and all the consumption limits are actually set by the payer himself, so even if there is no money in your relative card, as long as there is enough money in the payer's debit card, you can use it.
The relative card consumption funds will be deducted from the doctor's account. The system recommends a limited deduction method according to the usage habits of the doctor's shop, which can be switched by itself. If the limited deduction method fails, other payment methods will be tried to complete the deduction in turn. If the balance of the account and the bound bank card is insufficient, the deduction fails.
