Connecting the Device

The Desk 3500 comes with a connecter that splits into a RJ45 Ethernet connecting cable and an input for an external power port that we provide. The standard cord is 2 meters long. If you require a different connection, reach out to your Finix point of contact or the Finix Support team.

Using the Device

Connecting the terminal to power and an ethernet connection will automatically turn it on and set it ready to accept payments (after initial setup is complete.)


The device has separate payment mounts and stands available depending on your use case. The payment terminal can also print receipts.
