ID device in vehicles set up by club? (5,4)
I believe the answer is:
smart card
'id device' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'vehicles set up by club?' is the wordplay.
'vehicles' becomes 'trams' (tram is a kind of vehicle).
'set up' says the letters should be written in reverse (in a down clue, letters go up).
'by' means one lot of letters go next to another.
'club?' becomes 'card' (clubs is a playing card suit).
'trams' backwards is 'smart'.
'smart'+'card'='SMART CARD'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for smart card that I've seen before include "financial authorisation" , "ID with microprocessor built in" , "used to carry out financial transactions" , "piece of plastic that stores data" , "Piece of plastic with micro-processor" .)
