Every big purchase on HDFC can be converted to EMI. You make the EMI payment through the following ways. 

Standing Instruction: You can set standing instruction in your savings account which will automatically debit the EMI to be paid for the month. 

Net Banking: If you are to pay the EMI from another bank account, you can register HDFC credit card in the payee segment to make payment as per your wish. If you are an existing HDFC customer, you can make the payment using the net banking facility. 

HDFC Credit Card Bill Desk: You can use the HDFC Credit card bill desk to make payment from whichever bank you have the account. 

Besides the online methods, you can also use post-dated cheque option to pay your credit card EMI payment.
