A PPENDIX D – V-SMART O PERATIONS

Section D.1 – HOST Mode versus SLAVE Mode Operation

The V-Smart has two modes of operation that the Administrator needs to be familiar with.

These are HOST mode and SLAVE mode.

HOST MODE

HOST mode is the normal mode of operation and simply means that the V-Smart is waiting

for a smart card to be presented to the unit. When a smart card is “seen”, the card Site Key

(see next Appendix) is compared with the V-Smart’s Site Key. If they match, the template

is read from the card and the V-Smarts attempts a Verification operation. The top LED will

turn amber indicating the user should “PLACE FINGER ON SENSOR”. When a finger

placed, a live image is recorded. When the live image is done recording, the top LED will

go off. At this time, the user can remove their finger. The V-Smart will then compare the

live image against the template read from the smart card. If a successful match made, the

top LED will turn GREEN. A RED LED indicates a failed comparison. Once a Verification

attempt has been made, the card must be moved away from the reader and then brought

close again to re-attempt Verification.

SLAVE MODE

SLAVE mode is when the V-Smart is communicating with the PC. When a serial command

is received by the V-Smart on the AUX communications port, SLAVE mode is automatically

entered. While in SLAVE mode, the V-Smart will NOT make Verification attempts when a

card is “seen”. This makes it easier for Administrators to place the card, near the reader

and perform various operations like enrollments without the unit performing a Verification

just because a card is sensed. The V-Smart will return to HOST mode in one of two ways:

1) a command is sent to the V-Smart telling it to specifically return to HOST mode

2) 180 seconds have passed since the last communication on the AUX port

In VeriAdmin, when you bring up the SMART CARD MANAGER, the V-Smart is put into

SLAVE mode because a STATUS is sent to the ESI as the dialog is brought up. When the

user exits the SMART CARD MANAGER by pressing the OK or CANCEL buttons,

VeriAdmin will instruct the V-Smart to return to HOST mode.
