Process a payment

Accept card payments in semi-integrated mode from your SmartPOS terminal

This is the cashier’s main flow. From the Home tab you pick the Sale operation, enter the amount, the customer picks how to pay and the terminal handles the entire authorization on its own, with no extra action needed from the merchant’s system.

Before you start

Step 1 — Enter the amount

From the Home tab, tap Sale in the operations menu. The terminal shows the numeric keypad with a Sale header. Enter the transaction amount and tap the confirmation button, the blue check icon.

Step 2 — Tip

The terminal shows the customer the Add Tip? screen. The customer picks one of the preconfigured options, selects Custom to enter a free value, or taps No Tip.

The tip is added to the subtotal to form the total charged to the card, and it is recorded as a separate field on the receipt.

Step 3 — Installment selection

The app shows the Installment options screen. The customer or the cashier picks between:

Tap Confirm to continue.

Step 4 — Card presentation

The terminal shows the card-waiting screen with the confirmed amount and three entry methods. The customer presents their card however they prefer.

The cashier can cancel the transaction at any point from this screen by tapping Cancel Sale.

Step 5 — Digital signature

The terminal asks the customer to sign on the touchscreen. The customer signs with a finger or a stylus and taps Confirm. To start over, they use Clear and sign again.

Step 6 — Processing

While the terminal talks to the card network, the waiting screen appears with the amount in progress. This step usually takes 2 to 5 seconds with good connectivity.

Step 7 — Result

Approved

If the authorization succeeds, the app shows the Approved screen with a “charged successfully” message and generates the receipt automatically.

From this screen the cashier has three options for the receipt:

The Print button at the bottom produces the physical receipt on the built-in printer.

Declined

If the authorization fails, the terminal shows the Declined screen with the reason, when the processor provides one. The transaction is recorded in the Sales List with a Declined status and no Ticket # assigned.

What to do about a decline:

1. Check that the card has sufficient funds and is not blocked.
2. Try a different entry method. If contactless failed, try chip.
3. If the problem persists, ask the customer for another card.
