Update: This card is very low on rewards now. You get less than 0.5% return that too after paying Rs.75 redemption fees.

Better Opt for Citibank Indian Oil credit card

Hdfc Allmiles Credit Card was launched a year back.

Its a visa signature or world mastercard equivalent.

Each point is worth 75paisa 50paisa 25paisa now.
hdfc allmile credit card

While air mile option is that beneficial as there are other cards more beneficial than this for airmiles.
For money rewards you have to redeem for voucher which you can spend on hdfcbankallmiles.com for travel or recharge benefits.
Though the annual fees of this card is Rs.1000 but it get waived if you spend 1lac+ in a year.

Calculation: If you spend 1lakh rupees in a year using Hdfc allmiles card then you get annual fees waived.
Now the points you will earn on 1,00,000 is 1,00,000/150 * 3 = 2000points
In rupee value you can recharge or pay bill of mobile or dth using these points.
So it is 2000 X .75 25paisa each point worth= Rs.500
So every lac rupee spend on this card gives you Rs.1500 Rs.500 that is flat return of 1.5%0.5% on any type of spending without any limit on earning points.
I think it is most hopeless credit card in Indian premium card market considering it’s a signature card.

Priority Pass feature has been withdrawn from 1st April 2017. Only domestic lounge access is there in agreement with mastercard/visa.
Update: Hdfc bank recently downgraded their reward points its 50paisa only now. Hdfc Bank is known to launch very attractive credit card points to attract customers and slowly downgrade it. I am sure this 50paisa for each point will be devalued further in future. And now it’s 25paisa only. Shamelessly HDFC
