It’s not necessarily a scam. You can ask him first,
What is my name and what is my age?
When I apply for a credit card, I fill out which company I work for and what my monthly salary is.
What is the first investment amount?
If he can't answer any question, it's a scam.
If the answer comes out, it may not be true. Some scammers are well prepared. You can also ask the bank about it.
99.9% of such calls are from scammers. Banks will not allow you to issue a credit card without your knowledge.
