Call ICBC's credit card hotline directly, and ask the customer service if there are any account anomalies caused by repeated operations, or if someone will borrow your information for online transactions after your information is published online. Personally, I suggest that a number is bound to a Taobao account, which will not be troublesome, and secondly, you don't have to worry about the theft of another account that you don't use frequently. Now, as long as the credit card service basically doesn't send SMS notification service in 500 yuan, you won't know your credit card consumption ... by hand! Steal the whole family!
