- There are three LEDs located in the top center of the front panel.
- A red LED along with a long buzzer tone will indicate an unsuccessful authentication attempt.
- On the other hand, a green LED with a long buzzer tone will indicate a successful authentication. This LED will also flash briefly along with a short buzzer tone to indicate each touchpad key entry.
- A white LED will illuminate at the beginning of an authentication session such as the beginning of a keypad entry and turn off at the end of that session. Then either green or red LED with buzzer tone should immediately follow indicating a successful or unsuccessful authentication.
2. Capacitive Touchpad
- The keypad is located on the left half of the front panel and is organized like a telephone keypad. Each successful key entry will be indicated by a brief flash of the green LED and a short buzzer tone. The white LED may turn on if the key was the beginning of an authentication attempt.
- The * key (asterisk symbol on the bottom the left) clears out any previous keypad input, effectively working as a “clear/cancel” button. After a * key, a new PIN may be entered.
- The # key (pound symbol on the bottom right) serves as a “submit” button. This key will submit the previously entered keypad entry to the host unit for authentication.
3. NFC / RFID Antenna
- The NFC / RFID sensing antenna is located on the right side of the front panel. When using such keys, it is highly recommended to place the key as close to the surface as possible and hold it there at least one full second allowing the reader to fully read the data from the key.
Once the key is fully read, the reader will flash the green LED and illuminate the white LED. A green LED or red LED w/ a buzzer tone should follow shortly to indicate a successful or unsuccessful authentication.
4. USB Key Slot
- There is a USB key slot located in the bottom center of the reader. It is used for USB authentication methods such as U2F and OTP protocols. Most keys such as Yubikeys should be inserted with a touch element facing the user but specifics will vary depending on the individual model.
- Authentication flow with USB keys will vary depending on the available and pre-arranged protocol. OTP keys may simply be inserted into the slot and a button press on the key will initiate a request to the host unit.
- U2F keys will require a key inserted in the slot first and then a user account PIN entry on the touchpad to receive a key challenge from the host. Then the button on the key will need to be pressed by the user for the ‘test of user presence.’ Often when the key is waiting for the button press, it will flash its own LED on the key, if available, to prompt the user.
- Some USB keys pre-enrolled with its NFC data can simply be placed on the NFC/RFID antenna section for wireless transfer of data back to the host for the authentication request.
