function field_permission_example_field_formatter_view

Implements hook_field_formatter_view().

Here we output the field for general consumption.

The field will have a sticky note appearance, thanks to some simple CSS.

Note that all of the permissions and access logic happens in hook_field_access(), and none of it is here.
