A security device for a bill changer that greatly reduces the risk of the coinage within the changer from being robbed. The security device includes a support having a bill insertion slot therethrough. The support is adapted to be securely attached to a front surface of a bill reader with the insertion slot aligned with a corresponding slot of the bill reader. A moveable blade is mounted on the support and detaches foreign objects extending from an inserted bill. An actuator member, preferably comprising two solenoids, is connected to the blade for moving the blade across the insertion slot in response to validation of an inserted bill by the bill reader to detach any foreign objects therefrom. Alternatively, the device may comprise an electrically responsive switch member adapted to be connected to the bill changer for disabling the changer and preventing the operation thereof, a timing member responsive to electrical pulses provided by the bill changer during delivery of the coinage and a control member interconnecting the timing member and the switching member for operating the switching member to disable the changer when the timing member assumes an alarm condition.
