The credit cards issued by CCB are collectively referred to as Longka Credit Card, and of course they also include the IC credit cards of Hong Kong, Macao and Taiwan mentioned by the landlord.

The basic financial functions of Longka credit card include: spending first, repaying later, recycling credit line, installment payment, points exchange and other functions.

At present, this Hong Kong, Macao and Taiwan IC credit card issued by his family is a UnionPay single-currency card, which can be swiped by merchants marked with UnionPay logo. It is very good in Hong Kong, Macao and Taiwan, and there are many preferential activities of UnionPay. At the same time, the IC chip loaded on the card can encrypt the data in the card, which is unrepeatable. In addition to the original payment by credit card, the landlord can pay by credit card at the merchants indicated by "UPCash" and directly pay by credit card at the merchants supporting "Express Express Pay". Both payment methods are very convenient to use.
