Abstract

In interactive terminals such as an automatic teller machine, an identification card is often presented to the machine to initiate operation of the machine. It is important that only cards having the requisite width and stiffness be inserted in the card read slot in order to prevent jamming of the machine by vandals. This article describes a card gate which permits only cards of the requisite width to be inserted into the machine, yet freely allows these same cards to be ejected from the machine.

Identification Card Security Gate

In interactive terminals such as an automatic teller machine, an identification card is often presented to the machine to initiate operation of the machine. It is important that only cards having the requisite width and stiffness be inserted in the card read slot in order to prevent jamming of the machine by vandals. This article describes a card gate which permits only cards of the requisite width to be inserted into the machine, yet freely allows these same cards to be ejected from the machine.

Figure 1 shows the card gate mounted into the cabinet of a machine. Cards are inserted at throat 10 having a height slightly taller than the thickness of the card. Locking yoke 12 has ramps 11 at each side of the card path to be engaged by the edges of card 15 and raised as shown in figure 2. As the card enters the throat and raises yoke 12 clear of lock tab 13 on pivot bar 16, pivot bar 16 becomes free to rotate as shown in figure 3 to permit the passage of the credit card into the card reader. Figure 4 shows the action as the card is being returned to the user. As the card contacts the pivot bar 16, it is rotated clockwise causing ramp 17 to lift lock yoke 12. Card 15 continues outward and upon clearing pivot bar 16 continues to hold lock yoke 12 clear of pivot bar 16, which then returns to a normal vertical position by gravity. When the card is removed, lock bar 12 drops in front of lock tab 13 to prevent subsequent counterclockwise r...
