Description of motor-phobic person's electronic device (4,6)

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

'description of motor-phobic person's' is the wordplay.
I cannot really understand how this works, but
'motor' could be 'car' (informal term for car) and 'car' is found in the answer.
'person' could be 'reader' (reader is a kind of person) and 'reader' is found within the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
