Abstract: An autoteller accepts on a ramp exchangeable banknote cassettes which can only be opened at the predetermined angle of the ramp when a key assembly on the ramp is presented to a lock. The cassettes may only have the key assembly presented to the lock when not on the ramp at an angle to the horizontal, whereat opening of the doors on the cassette is prevented by a blocking bar swinging to engage a notch in the opening mechanism to prevent operation of the opening mechanism. A processor in the autoteller accepts a password from an internal keypad, enters a wide access bank service routine if a first password is provided and a restrictive access third party service routine if a second password is provided, shutting down the autoteller if no correct password is provided within a predetermined number of tries in a predetermined time.

Abstract: A tamper proof pop rivet assembly comprises a base plate having base plate holes of a greater diameter than that of the barrel of a pop rivet and of a greater diameter than that of the flange of the pop rivet and further comprises a top plate having top plate holes of a greater diameter than that of the traction pin of the pop rivet and of a lesser diameter than that of the barrel of the pop rivet. The top plate is spot welded to the base plate to sandwich the flange of a pop rivet therebetween. The assembly can be used as a replacement for a conventional pop rivet assembly and shows visible signs of any attempt at drilling-out or replacing the pop rivet.
