I want to collect bank account numbers and IFSC of my employees to transfer their salary, but due to your policy, my account will be suspended.

We do not allow for the collection of credit card or bank account details through forms.  As per our terms of use:

Collecting Sensitive Information. You may not use the JotForm to collect certain types of sensitive information, including but not limited to credit card information and any type of login credentials. You may collect some sensitive information such as social security numbers or driver’s license numbers, but you are required to use best security practices of JotForm including SSL and Encrypted Forms features. You are solely responsible for compliance with any data protection and privacy laws and rules applicable to the sensitive information.

We need to become much strict on this due to becoming PCI compliant. If you require payment authorization, that can be done through one of our many payment processors:
