The concept of the credit card was first used in the United States of America. There were debit cards that used to get deducted immediately after the purchase or the transaction was made. In the case of the credit card, if one does not have the exact amount of balance in the account, then the transaction can be made on a credit basis.

There are different types of banks where credit cards are offered at different rates of interest with varying kinds of rules, regulations, and facilities. The most widely used credit card is the travel credit card. Travel credit cards are well served with cashbacks and the types of bonuses. There are other types of credit cards used for filling the fuel and the diesel or the CNG gas in the vehicles in the piping or the fueling station. Reward, shopping and the secured credit card can be used for other required necessities. There are few criteria that a person will have to meet to become eligible for getting a credit card.
First and foremost is age. The age criteria have been involved because there is a concept that below or above a specific age person loses financial independence, and this will be an issue in repaying the loan or the amount of the credit card as well. The legal minimum age in most of the banks and the NBFCs is 18 years of age if we see into that of the maximum period that can be provided to that till 60 years or near about it.
Now the next thing which one needs to keep an eye on is the credit score. A credit score is the type of score where the past repayment pattern and the style of the paying can be seen or examined and based on which it will be decided that the bank or the NBFCs will provide the loan. It is advised that a person having a bank account with the bank can avail of the credit card if the person's credit score while maintaining the performance is about 650 or above. If the transaction and the repayment have been made carefully at the proper time, then there will be less interest in almost most of the thing as there will not be the risk of the repayment due to the good credit score. Credit Cards Schemes in Karnataka Bank have such offers which are provided to the old and loyal customers. In most of the cases, it has been noticed that casually people avail themselves of the other services and are unable to repay on time thus this is the reason where the credit score takes a negative hit which can affect the credit score and the credit card or other types of the loans to avail.
The income support or the employment status is also essential as the regular earning will make the person pay regularly. It also depends on how much the person is deserving and based on which the loan EMI should be calculated. If the person is earning less than the loan tenure needs to be longer or more so that the EMI burden will be less on the loan borrower. In contrast, either side of the coin, if the earning is more, the loan amount can be higher with less rate of interest, and the loan tenure will also decrease as the EMI will be more affordable to that of the customers.
Conclusion:
Net monthly income of the customers is required to have the minimum salary of Rs 15000 in most cases, while it might be different in different banks and the NBFCs. The income tax returns are required in the case of the self-employed or the business professionals as well. If we look into the different types of banks, the interest rates in case of the credit cards are different in other financial institutions. For example, the case of the Unnati credit card provided by the State bank of India will have an interest rate of 2.50%.
