What are the implications of using a lower interest rate credit card for a person's credit score and financial history?

Using a lower interest rate credit card can have positive implications for a person's credit score and financial history, as long as they use the card responsibly. Making timely payments and keeping the balance low can help improve the credit score over time. On the other hand, missing payments or carrying a high balance can have a negative impact on the credit score and make it harder to qualify for credit in the future. It's important to use the card wisely and avoid overspending or carrying a balance that cannot be paid off in full each month.
