'old it feature fills' is the definition.
I can't tell whether this defines the answer.

'home-worker with fear' is the wordplay.
'home worker' becomes 'carer' (someone who provides care in the home).
'with' indicates putting letters inside.
'fear' becomes 'dread' (dread is a kind of fear).
'carer' enclosing 'dread' is 'CARD READER'.
