Many times cardholders only pay the minimum amount due to restore their credit limit. Such consistent behavior will increase the interest cost on the credit cards making it eventually difficult for the cardholder to meet their commitments. 

Default in paying credit card dues is also reported to credit rating agencies which negatively impacts the credit report and the credit score effectively closing the doors to a new line of credit. Hence it is essential to be cautious of the debt trap of credit card.

The risk of fraud through credit cards although low is always present. It is important to not disclose the CVV and the PIN to any other person to ensure the safety of the card. 

d. Fees and charges

The fees and charges on credit cards are quite high which often outweigh the benefits or the rewards offered by the credit cards. 

f. Possible negative impact on credit score

Credit cards have a direct impact on the credit score of the person. Any adverse use of the credit cards or default in payment of dues will negatively impact the credit score and harm the credit profile of the cardholder.
