Clock out from a non-licensed iPad

We have one iPad terminal for taking orders.

We have a team of drivers, bakers, pastry chefs, cooks, etc. It's totally unrealistic for them to be coming to the front of the store, interrupting front staff when there's a lineup and transactions underway, to then exit to the POS main screen and clock in/out

I have a backup tablet that I'd like to put in the back for the 2/3 of our staff that aren't front staff, so they can clock in/out

This backup terminal does not need any functionality on it except clocking in/out, and as you can imagine it's wasteful for us to purchase a whole Enterprise license just to allow back-end employees to sign in and out.

This is a feature we had on our old POS and while I love the new capabilities we get from Linga, we really really need this one!
