Final answer:
The information that does not affect a credit card company's decision includes existing credit card companies and the number of credit cards.
Step-by-step explanation:
The information that does not affect whether a credit card company will give you a card includes: Which companies you have credit cards from already, How many credit cards you already have.
However, your payment history, How much debt you have, and other factors such as your credit score and income will influence a credit card company's decision to grant you a credit card.
For example, if you have a history of late payments or a high amount of debt, the credit card company may view you as a higher risk and may be less likely to approve your application.
