hard cash

'notes heard' is the definition.
I can't judge whether this definition defines the answer.

'when entering church not electronic' is the wordplay.
I cannot quite see how this works, but
'when' could be 'as' (eg 'when I walked' means 'as I walked') and 'as' is found within the answer.
'church' could be 'ch' (common abbreviation) and 'ch' is found within the leftover letters.
The remaining letters 'hard' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

(Other definitions for hard cash that I've seen before include "Ready money" , "Coins and banknotes - not a cheque" , "Coins and notes, not cheques or promises" , "Not plastic!" .)
