Fish included in simple product lines? (7)

Ross

I believe the answer is:

barcode

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

'product lines?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'fish included in simple' is the wordplay.
'fish' becomes 'cod' (type of fish).
'included in' means one lot of letters goes inside another.
'simple' becomes 'bare' (synonyms).
'cod' placed inside 'bare' is 'BARCODE'.

Can you help me to learn more?

(Another definition for barcode that I've seen is " may be scanned".)

I've seen this clue in The Times.
