If others know my UnionPay card number and password, can I receive information when I buy things online?

In that case, let's see if you have opened the transfer notice. If yes, your consumption information should be sent to you in the form of SMS, such as how much is your UnionPay card with a suffix of * * * *. Generally speaking, even if he knows this, it is useless. Some people even need mobile phones to receive dynamic verification codes. If he has your mobile phone, there's nothing he can do. If he receives it, he can spend it smoothly!
