The flash payment card is technically safe. In fact, when it is used, there is a security risk that it can be paid directly without a password and stolen. If you are worried about being stolen, you can take the following measures:

1, the risk is controllable: offline merchants can open a small amount of confidential visa-free service or set a limit. A single credit card cannot exceed 300 yuan. The daily credit card limit is generally 1000 yuan, and citizens can set the lower limit by themselves.

2. Reduce the limit of flash payment: you can call the customer service phone of the issuing bank or go to the counter of the bank outlet to reduce the limit of the "flash payment" function.

3. Get compensation: If the card is stolen after being lost, the cardholder can apply for compensation after reporting the loss. After investigation and evidence collection, the cardholder can get some compensation.
