Confidential Data

I want to hide PAN and Aadhar Card numbers after saving the data. How should the confidential data be saved?? any datatype??

There is no specific data type I think but you can try to create a control similar to password field and use it. Other option is to hide it for users other than the employee whose data it is.

Thank you @Pawan for the response. Will try to create a control like password.
