As of my last update in September 2021, the RBL Bank SuperCard was considered a popular credit card option with several benefits and features. However, the specific features and benefits of the SuperCard, as well as its overall reputation, may have changed since then.

The RBL Bank SuperCard was known for offering various benefits such as:

Flexibility: The SuperCard was designed to act as both a credit card and a cash card, offering withdrawal options and an interest-free period on cash withdrawals.

Reward Points: Cardholders could earn reward points on every transaction, which could be redeemed for various offers, discounts, or gift vouchers.

Zero Fuel Surcharge: Some versions of the SuperCard provided a waiver on fuel surcharges at fuel stations.

Contactless Payments: The card featured contactless payment technology, enabling faster and convenient transactions.

Easy Bill Payments: Cardholders could use the SuperCard to pay utility bills and avail of easy EMI options on significant purchases.
