In today's rapidly changing era, credit cards are a necessity and a cornerstone of financial flexibility. They act as a revolving line of credit and these credit cards permit users to make purchases, pay bills and withdraw cash up to a pre approved limit.
Due to the seamless and smooth nature of credit card usage, their popularity is rising. This is primarily driven by the cashless economy and the need for quick access to funds. The credit card count in the country has more than doubled in five years, while debit card growth remained modest.
Digital payments surged 94-fold since 2013, showcasing the country's rapid fintech transformation and UPI-led expansion. Therefore, as more people embrace digital finance tools for the first time, credit cards are becoming a key part of this shift, especially for those seeking convenience, flexibility, and credit-building opportunities as first time users.
Highlighting this trend, Anup Agarwal, Co-founder at Kiwi, said, 'For first-time users, a RuPay credit card on UPI is a great way to start their credit journey. It allows convenient payments at local stores while offering the benefits of credit. Using it for regular expenses and repaying on time can help build a strong credit profile.'
A credit card is a plastic or virtual payment tool which is issued by a banking institution or NBFCs. It permits users to borrow money for purchasing goods or services. It includes a preset spending limit, interest terms, and a billing cycle.
A credit card permits users to borrow from a bank for purchases, to be repaid within a set period. Each card has a credit limit. Paying the full bill by the due date can help avoid interest, but carrying a balance attracts charges. Credit cards are widely used for online shopping, travel, and bill payments in the nation.
As a prudent and well informed aspirational user of a credit card you should check your eligibility before applying. Most credit card issuers require elements such as a minimum age, income level, credit score along with clean repayment history to permit you to use their credit card. Your credit score plays a vital role in approval and credit limit.
A good credit score i.e., a score of over 750+ generally helps applicants get better terms. That is why you should always review your credit report for mistakes and errors before submitting an application for a new credit card. Understand the fees: Credit cards may include joining fees, annual charges, hidden amounts and penalties. Some issuers waive initial charges, but check the terms carefully. If in doubt, carefully discuss with the customer support team of the credit card issuing authority and resolve your doubts.
