So obvious options are maybe to look to log code within ticket used on and try and validate that way.
Or have a list and mark off as used.
Not sure how simple the first would be as not done in style you have opted for, when done something like that coupon was generated from an initial transaction so code included origional ticket number giving an easy point of reference for checking.
