Abstract
A smart card is provided having a removable integrated circuit. The integrated circuit is mounted on a semiconductor chip assembly which is locked within the smart card. The semiconductor chip assembly is configured so that once it is locked in place, it may only be removed with a special tool. The special tool allows the locking mechanisms holding the semiconductor chip assembly within the smart card to be disengaged. Attempts to remove the semiconductor chip assembly without the special tool may result in damage to one or both of the semiconductor chip assembly and the smart card. The semiconductor chip assembly may be mounted through the side of the smart card or through one of the faces. A security label applied to the smart card and the semiconductor chip assembly provides additional security with a visual indication of tampering with the semiconductor chip assembly.
