From the patron's detail view, the staff member can, as an extra security measure, ask the patron to validate their PIN code before, for example, disclosing information or carrying out actions on the patron's behalf. This is done by clicking "Validate PIN" at the bottom of the patron's detail page.
A dialog box then opens with a blurred background, where the PIN code can be entered.
If the PIN code is incorrect, the dialog box remains open and an error message is shown.
If the PIN code is correct, the dialog box closes and a notification is shown confirming this.
