There are many ways to apply for a credit card, and door-to-door sales is one of them, which is quite reliable, but we should pay attention to the following points:

1, the person who handles it needs to have all the certificates for bank work;

2. When handling, you can't give any of your original documents to the other party;

There is no need for them to apply for credit card approval at home. Whether the credit card can be approved or not, and the amount should be decided according to the actual situation;

If the salesman has nothing, as long as you show your certificate, it is not credible, mostly a liar, so pay attention.

Better go through the bank counter or something. Of course, if you don't want to do it, don't do it, or you will charge an annual fee or something.
