Credit Card is a type of a payment card issued by the bank to enable the cardholder to pay for the goods/services based on the cardholder’s accured debt which is paid with interest on a monthly basis.
It allows one to make purchases by borrowing money to a certain limit, higher purchasing power, and more rewards.
And, yeah, a person can hold more than one card of the same bank and account, but they might be of different terms.
If one has more than one credit card, then they can juggle the expenses smartly minimising the interest-free period benefit.
Having multiple cards can give benefits like a low credit utilization, more rewards, etc.
