Analysis and research of card ticket's security based on card scraping & vending technology

In a new card ticket scraping and vending device of TVM (Ticket Vending Machine), the interaction between the scraper and the super-thin & non-contact IC card was analyzed by FEM (Finite Element Method) in this paper. A new improved project for ticket ejecting module of TVM was proposed to overcome the defects of traditional method of vending tickets with friction wheel, which hurts the cards easily with low control accuracy. Finite element models of the scraper-ticket collision in two types were created and the structural transient of the card was analyzed. The ticket's security was verified by analyzing the maximum stress of the ticket and the deformation at the location of the chip.
