Antenna Housing LED
Inside the card reader’s housing a LED is mounted which can be used to let the user know that card
data has been read and this data is presented to the server. The LED will also be used to show an error
has occurred, by using different blink patterns.
Blink patterns
In case of an error situation the LED will blink with an irregular pattern.
The number of times the LED blinks between the longer 'on' (or 'off') pulses is an indication for the error
code.
