Debit Cards

Yes, you can get a 0.4% return as well. The majority of customers receive their returns by carefully using their points to purchase particular goods or coupons, such as HDFC's "Gold Catalogue" for particular debit card types or their SmartBuy platform.

Check the SmartBuy portal and the perks of your HDFC debit card to obtain the best redemption possibilities.

It has a nominal annual fee (around ₹220 + taxes). For international transactions, you can expect 3.5% charges. Generally domestic usage is free.

Perks include loyalty points on spending and potential discounts at partner merchants and basic insurance, but travel-specific benefits are limited for international use.

Your transaction may be declined because international or online transactions are disabled by default, the card type is unsupported, or there is an insufficient balance. Log in to your bank's app or net banking and enable online and international transactions in card settings.
If the issue persists, contact customer support or use an internationally accepted card.

The bank doesn't offer any cashback directly, but there are some third-party apps like Cred, Paytm, and PhonePe that give you benefits or cashback after you pay your bills.

There are some platforms that offer cashback for HDFC debit card users: Cred, Paytm, and Amazon Pay, and GPay.

To check any active offers, you can visit the HDFC SmartBuy website (https://offers.smartbuy.hdfcbank.com/) or the HDFC Bank app for specific cashback deals. Or you can check the reward programs and offers available on popular payment platforms.

Both banks offer competitive corporate salary accounts that come with premium benefits. ICICI has good online banking service and customer care service. HDFC offers high interest rates on savings. 
So while selecting the premium card for yourself, choose the card that gives you good rewards, a daily cash withdrawal limit, travel benefits, and a good cashback facility.
Both cards offer excellent services. So choose the card that fits according to your spending habits.

Both cards offer verity of benefits and have almost the same features. But I would suggest the HDFC Platinum Debit Card to you. As this card gives you more rewards points and have high transaction limits. This is a perfect card for you.

You seem right as Platinum International debit card works for that. I have done the same and have the same experience. All you should know is about charges; i.e. cost may include Issuance fee, annual maintenance fee etc. Also for overseas cash withdrawals, they charge Rs 100 with 3.5% + GST of the transaction amount.

That's very strange. There have also been reports of surcharges applied to debit card purchases of fuel. It's important to review the Axis Bank's conditions. Have a word with customer care and ask for the clarification or a refund.
