Set up a Landi C20 Pro (Viva Wallet)

The Landi C20 Pro runs both the POS and the Viva Wallet payment app on one device,
so orders are placed and paid on the same screen. This guide sets one up.

That makes it a standalone terminal. The C20 Pro can also be used as an
external, customer-facing terminal alongside a separate till — if that is what you
are building, read Which terminal setup do you need? first, because the answer in
step 2 changes.

Before you start

• The C20 Pro is switched on, connected to Wi-Fi, and the Viva Wallet app is installed and activated on it.
• Do this on the C20 Pro itself — this is the device that will take the orders.
• If you are connecting a cash drawer, plug it in before you start, and know its make: Star, Oscar, or another brand.

1. Open the payment terminals list

On the C20 Pro, open the menu at the top left and choose Payment terminals. The list shows every terminal
already known to this shop, with its provider, ID and model under the name.

Tap New payment terminal. If the POS first shows Choose provider, tap
Viva Wallet, then tap Continue.

2. Choose the setup

The POS asks where the Viva Wallet app is installed. On a C20 Pro it is installed on
this device — the same one you are tapping on.

Tap Yes, installed here, then tap Continue.

Answering No, installed on another device tells the POS to send payments to a
separate terminal. The checkout will then wait for a device that does not exist.

3. Choose the Landi C20 Pro

Tap Landi C20 Pro, then tap Continue.

Pick the model you actually have. It decides which steps follow — the C20 Pro is
asked about its built-in printer and its cash drawer, which a device without them
never sees.

4. Decide whether to print on the device

The C20 Pro has a built-in receipt printer. To print customer receipts on the device
itself, tap Yes, use built-in receipt printer. To print them on a separate
receipt printer, tap No.

Tap Continue.

5. Connect a cash drawer

If you chose the built-in printer in step 4, the POS asks whether a cash drawer is
connected to it. Choose the make of drawer you have attached:

• Not connected to cash drawer — no drawer, or the drawer is attached to a
  different device.
• Star or Oscar — pick the brand printed on the drawer.
• Generic — any other make.

Tap your choice, then tap Continue.

If the drawer stays shut on the first cash sale, come back and try a different make
before assuming the drawer is faulty — the brands use different opening signals.

6. Name the device

Give the device a name your staff will recognise, such as Front counter or Bar.
With more than one till, the name is how they are told apart in reports and in the
terminal list.

Tap Continue. When it worked, the POS shows Payment terminal created
successfully! and takes you back to the terminal list.

7. Finish setup on the device

8. Check it works

1. Ring up a test item and choose Card.
2. Complete the payment with a real card, then refund it from the order.
3. Check the receipt printed where you expect it to.
4. If you connected a drawer, confirm it opened during a cash sale.

A payment is only complete when the POS shows it as Settled. If it stops at any
other status, the customer may not have been charged.

Check the printer prints

You do not need a sale to test the printer. Open the menu at the top left and choose Receipt
printers, tap the printer, then tap PRINT TEST RECEIPT.

The same screen tells you two more things worth knowing before the first busy
service. Last printed says whether this printer has ever produced anything — a
printer reading Never after a test print has not received it. The Kitchen
printer switch, when on, makes this printer print kitchen orders only.
