One-card small-amount secret-free visa-free is a small-amount fast payment service provided by UnionPay, which is opened by default. When a financial IC card or mobile device with the function of "flash payment" is used to conduct a transaction below a certain amount (single transaction in China 1000 yuan, with a daily limit of 2,000 yuan, which is subject to the local limit overseas), payment can be completed by simply "waving the card" near the "flash payment" sensing area.

Credit card small secret visa-free is the default opening. When you use a financial IC card or mobile device with the function of "flash payment" to conduct a transaction with a certain amount (domestic 300 yuan or 1000 RMB, overseas is subject to the local limit) or less at a designated merchant, you only need to put the card or mobile device in the vicinity of the "flash payment" sensing area of an acceptance terminal such as a POS machine to complete the payment.
