Does the landlord use a UnionPay chip card? I am using this card. This credit card has the function of "flash payment". "Small confidential visa exemption" is not a business launched by CCB. This is a fast payment service provided by China UnionPay for cardholders, so even if it is not a credit card of CCB, like Agricultural Bank of China, Bank of Communications and China Merchants Bank, as long as there is a flash payment function, it is all the same. With the Longka credit card with the logo of "Flash Payment", when a designated merchant conducts a transaction with a certain amount (RMB is within 300 yuan, subject to the local limit overseas) or less, it is only necessary to put the card or mobile device near the "Flash Payment" induction area of the terminal to complete the payment. In the payment process, you don't need to enter a password or signature. However, this payment method is limited. The cumulative transaction limit of a single card for the small-scale confidential exemption and visa-free service of Longka Credit Card and UnionPay Chip Card is below RMB 1 000 (inclusive) in China, and the local limit shall prevail overseas. The landlord can also check the list of small secret visa-free merchants through the UnionPay website.
