The IDFC FIRST WOW! Credit Card is a secured credit card backed by a fixed deposit with IDFC FIRST Bank. It carries absolutely no joining fee and no annual fee, making it lifetime free. The card runs on the Visa Infinite platform, giving it global acceptance at millions of merchants and ATMs. Its headline benefit is 0% forex markup on every international transaction, whether you are swiping at a store abroad or buying from an international website in India. Most Indian credit cards charge 3.5% on foreign currency transactions, so the WOW! card saves roughly ₹350 per ₹10,000 spent overseas.Reward points are earned at 4X on online, offline, and international spends, where 1X equals 1 reward point per ₹200 spent. Each reward point is worth ₹0.25, putting the effective return rate at 0.5% on regular spending. Insurance premiums, utility bills, FASTag recharges, and railway tickets earn at the lower 1X rate. Fuel transactions, EMI conversions, and cash withdrawals earn zero points. Points never expire as long as the card is active, and you can redeem them at point-of-sale terminals, online checkouts, or through the FIRSTREWARDS portal. A ₹99 plus GST fee applies per redemption transaction.The fixed deposit backing the card earns 6.3% p.a. interest, so your money continues to grow while serving as collateral. Your credit limit is set at minimum 100% of the FD value, and you can increase it anytime by linking additional FDs through the mobile app. ATM cash withdrawals are interest-free for up to 45 days at both domestic and international ATMs, with a flat ₹199 plus GST fee per withdrawal. The card also bundles ₹2 lakh personal accident insurance, ₹25,000 purchase protection, and ₹25,000 card liability cover.Eligibility is straightforward: Indian citizens aged 18 to 80 with a permanent address can apply by creating a minimum ₹20,000 FD.

The entire application is digital with instant card issuance. For users who want more, IDFC FIRST also offers the WOW!
