User Guide

This guide explains how to use the DX8000 in day-to-day operations. It covers the most common actions performed directly on the terminal, from initiating payments to handling transactions after completion.

Starting a Payment

To start a payment, open the payment function from the terminal home screen or from the menu.

Enter the transaction amount and confirm it on the device.

Tips (Optional)

If tipping is enabled on the terminal, the customer may be prompted to add a tip before completing the payment.

Depending on the setup, the terminal may offer:

predefined tip options
manual tip entry
the option to continue without a tip

The tip flow is optional and only appears if it has been enabled for the merchant.

Completing a Payment

Once the amount has been confirmed, the terminal prompts the customer to complete the payment.

Depending on the enabled payment methods, the customer may be able to:

tap a contactless card or wallet
insert a chip card
swipe a magnetic stripe card
use a QR-based payment method

Card and Wallet Acceptance

The DX8000 supports the standard card-present payment methods used in Switzerland.

This may include:

contactless cards
chip cards
magnetic stripe fallback where applicable
mobile wallets such as Apple Pay or Google Pay

QR-Based Payments

If QR-based payment methods are enabled, the payment screen may also present a QR flow.

This behavior may vary depending on which QR-based payment methods are activated on the terminal. For Alipay and WeChat Pay, a separate QR code has to be initialized. By default, the TWINT QR code is displayed.

Manual Card Entry

Manual card entry may be available in specific configurations. In such cases, the terminal allows the merchant to enter:

card number
expiry date

This function is generally restricted and may not be available on all setups.

Dynamic Currency Conversion (DCC)

If DCC is enabled and the customer uses an eligible foreign card, the terminal may offer a currency choice during the payment flow.

The customer is then shown:

the transaction amount in the local currency
the converted amount in the card currency
the exchange rate and additional information

The customer can choose whether to pay in the local or card currency.

Approval or Decline

Once the customer completes the payment, the terminal sends the authorization request through the payment network.

The transaction is then either approved or declined.

If approved, the transaction is stored for later submission and settlement
If declined, the customer is informed and the payment can be retried

After a successful payment, the terminal provides the corresponding receipt flow.

The following receipts can be printed or displayed:

merchant receipt
customer receipt (also available as digital receipt, depending on setup)
