We got a instruction from SLIM to remove the credit card storing / swiping in Infrasys due to credit card safety.
So as per my understanding it should also applicable to existing credit card removal too.
Please do let me know if there is any complication in removing existing credit card detail.
I do have asked our Management to check if it is fine for them to remove the current credit card records too to confirm you again.
Meanwhile do help to stop the credit card swiping first.
