Credit cards come under unsecured loans. Having too many unsecured loans in one’s credit mix will reduce their credit score. Additionally, having too many credit cards might be difficult to manage. In case one misses to pay a credit card bill, then a late payment or non-payment of a bill might drag down the score by 100 plus points. Hence, it is advised that individuals limit their credit cards to 2 or max 3. This will help them in managing their credit better.
