Is the landlord sure that the e-cash account has been returned? E-cash account is a financial function of IC chip card, which can be paid by credit card in the merchants with Express Pay logo, but the e-cash account has no quota and money, so it must be recharged first, and the recharge method is called deposit. For example, I use a CCB chip credit card, and the maximum deposit amount is 1000 yuan, which must be cash or credit card limit deposit. The landlord now says that the money should be returned to the electronic cash account and registered, and it can't be taken out unless the card is cancelled. But there is no need to cancel. The money is still in your credit card. It won't be gone. In the future, when I see a shop with flash payment, I will use it up as long as I swipe my card. For example, McDonald's and familymart can now pay by flash, and there is a 6.2% discount every June 1 -2. As for the credit card arrears, all you have to do is pay one more sum. There will be no problem. Don't worry.
