The word 改札 is a compound word formed from two kanji: 改 (kai), which means "to correct" or "to revise," and 札 (satsu), which means "a card," or "a ticket." Originally, tickets were manually checked, and the process involved verifying and possibly "correcting" the ticket to ensure it was valid. The word evolved to describe the area and the process of checking tickets.
