A data carrying badge 10 has an opening 12 through it, into which a latch 14 swings as badge 10 is moved in direction A into badge reader 16. The badge 10 cannot be completely inserted into reader 16 for reading purposes, unless badge 10 is inserted into reader 16 in proper disposition with opening 12 in registry with latch 14.

When badge 10 is inserted into slot 18 of reader 16, it abuts against slider 20 and moves slider 20 along its guide rails 22 against the action of spring 24. Spring 24 is fixed with respect to a stationary member 26 and is connected to slider 20 by flexible band 28 that extends from spring 24 around roll 30 to slider
20. Latch 14 is swingably mounted on slider 20 by shaft 34. A torsion spring 36 extends around shaft 34 and has its ends fixed with respect to slider 20 and latch 14, for yieldably holding latch 14 downwardly to a limit of its movement.

Opening 12 is offset to one side with respect to the longitudinal center line 10a of badge 10, and latch 14 is in alignment with opening 12 when badge 10 is inserted into slot 18, face side 10b up and front end 10c leading; and, as badge 10 moves slider 20 against the action of spring 24, latch 14 abuts against a stationary part 38 and is swung upwardly against the action of spring 36 so that latch 14 enters opening 12.

If badge 10 is inserted back end 10d first or upside down into slot 18, hole 12 is not in alignment with latch 14. As badge 10 moves slider 2...
