selected, a Wiegand sequence shall not be sent to the Access Control

System on biometric failures.

 Fail Site Code: a failure code may be activated and selected. This

code shall supersede the site or facility code portion of the Wiegand

string for all failed authentications that occur at the reader. When this

option is not selected, a Wiegand sequence shall not be sent to the

Access Control System on biometric failures.

 On Fail Send Inverse Parity: when activated, a failed authentication

shall result in the Wiegand sequence being sent to the Access Control

System with the parity bits inversed to indicate failure. This option should

not be selected unless the Access Control System performs parity bit

calculation and supports this feature.

13.6. Extended ID

The V-Smart reader shall support Wiegand formats, which allocate up to 64

bits for the Card ID. Because Bioscrypt fingerprint templates by default use

only up to a 32-bit ID, any Wiegand Formats which allocate more than 32 bits

to the ID number shall require the V-Smart to be in a special Extended ID

mode, which adds an Extended ID field to the fingerprint template. This field

actually uses the Employee ID field (not shown in VeriAdmin) and the

Password field (not available on a V-Smart).

For Extended ID support, the V-Smart shall require firmware version 7.30 or

greater with a VeriAdmin software version of 5.30 or greater. Also, a Custom

Wiegand Format file or Pass-Thru Format shall be required to support

Extended IDs. For more information on this feature, please contact Bioscrypt

Technical Support.

13.7. Duress Signals

The V-Smart reader shall support a Duress Finger Mode which offers users a

way to indicate a duress situation (such as being forced to open a door) by

authenticating with a specially designated “duress finger”. An individual

fingerprint template may be specified as such by selecting the “Make Duress

Finger” option during enrollment. One smart card may be used for both

duress and non-duress finger templates. When a successful authentication

occurs with such a template, the reader shall send the Wiegand sequence to

the access control panel in reverse bit order. The Access Control System can

then respond with the appropriate action (alerting security personnel,

sounding alarms, etc.). To fully support this feature, the access control panel

must also support reverse-bit Wiegand sequence duress signals.
