card reader

I'm a little stuck... Click here to teach me more about this clue!

'electronic device' is the definition.
(device used to read bank cards)

'filling nurse with fear?' is the wordplay.
'filling' indicates putting letters inside.
'nurse with' becomes 'carer' (I've seen this before. I am not sure about the 'with' bit.).
'fear?' becomes 'dread' (dread is a kind of fear).
'carer' placed around 'dread' is 'CARD READER'.

Can you help me to learn more?
