Using the Contactless GuardDog
The contactless GuardDog operates with a MIFARE contactless smart card, which is
the industry standard. This card complies with ISO 144443A.
1. Hold the contactless smart card close to the top of the GuardDog. The card must be 4 cm
(2
″
) or closer. (See Figure 5.)
The LED turns amber when the GuardDog is reading the card.
2. After the “chirp” and when the Fingerprint Sensor LED is blinking green, place your
finger on the sensor.
The LED turns amber when the GuardDog is scanning your finger.
3. After the chirp and when the LED turns off, remove your finger.
The GuardDog emits three very quick chirps and both LEDs blink green to indicate that
you have been successfully verified.
If the GuardDog emits only a single chirp and the Fingerprint Sensor LED starts to blink
green again, the GuardDog was unable to verify you. Reposition your finger and repeat
step 3. If, after three tries, the GuardDog cannot make a verification, both LEDs blink red
and the unit emits three long beeps. See “Finger Selection and Placement Tips” on page 10
for more information about ensuring successful verification.
