A boundary scan compatible device includes functionality for use in diagnosing the presence of bridging faults within associated circuitry. The module includes a first edge for contacting a first of the opposed walls and a second edge for contacting a second of the opposed walls. When a bar code, symbol is scanned by a laser beam focused within the first focal zone or scanning range of the system, the pass-band filter structure associated with this focal zone or scanning range is automatically switched into operation using a control signal produced by determining the spot speed of the laser scanning beam producing the analog scan data signal being processed. The smartphone reads the information on the chip and requests an issuerauthenticator to validate the note. The conductive layer is disposed between the first barrier layer and the second barrier layer.
