My experience was not about parking ticket but Touch & Go. Once at toll booth, in front of me, a Korean driver entered the Touch & Go lane without the card. He came out from the car and asked , wanted to borrow my card. He paid the toll amount to me and I gave him my card. After using it, the barrier opened and he returned the card to me. 

Next came my turn, I used the same card but was rejected. Helped  another person, now I got stucked myself. Went looking for a staff there and she told me that the same card cannot be used at the same spot more than once within a short period of time. Then she manually swiped my card and opened the barrier.
