Stolen, as bank card may be? (6)
I believe the answer is:
swiped
I believe this clue is a double definition.
'stolen' is the first definition.
(swiping is a kind of stealing)
'as bank card may be?' is the second definition.
(as in swiping a bank card to make a payment)
(Other definitions for swiped that I've seen before include "Struck; stolen" , "Hit with swinging blow, or slangily stole" , "credit card may be processed thus" , "Nicked (sl.)" .)
