Dear Hassan, once you click on Payment mode, you will get options of few prominent banks. Do not worry because you dont see Indian Bank option there. The interface is designed such that onle few banks will be shown as optiins. Click on any bank and you can make payment using your Debit Card by clicking on 'Other Bank' option. After the payment is successful, a confirmation page is generated and you need to save the details for anybfuture reference. This will be also sent to your registered Email. Generation of a confirmation page is a proof that your application has been successfully submitted.
