If tipping is enabled, the customer may be asked 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

A920 tip options and manual tip entry

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

Completing a Payment

Once the amount has been confirmed, the terminal asks 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 A920 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 show a QR code.

By default, the standard QR-based payment method is displayed. If alternative QR-based payment methods are active on the terminal, the merchant can change the displayed method directly from the payment screen.

To change from the standard QR method to an alternative method, press the green button with the three dots on the payment screen.

Manual Card Entry

Manual card entry may be available in specific configurations. It is not the normal fallback for standard card payments.

For regular card acceptance, the expected order is:

contactless
chip and PIN
magnetic stripe fallback, where applicable

If manual entry is enabled, it becomes available on the payment screen after the transaction has started. The merchant can open it by pressing the yellow icon on the payment screen and selecting manual PAN key entry.

The terminal may then ask for:

card number
expiry date
additional transaction data, depending on the setup

This function is usually restricted and mainly relevant for special use cases such as gift card or MPKE-related flows. It may not be available on all terminals.

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 shown:

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

The customer can then 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 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

Receipts

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

The following receipts can be printed or displayed:

merchant receipt
customer receipt, also available as a digital receipt depending on the setup

If no customer receipt option is selected, the terminal automatically prints the customer receipt by default.

Both receipts contain the main transaction details, such as date and time, masked card number, transaction reference, authorization code, and total amount.

The merchant receipt usually contains more operational information for support and reconciliation. The customer receipt is the shorter cardholder copy.

QR Receipt

On terminals that support QR receipt, the customer receipt may be displayed as a QR code instead of being printed.

The customer can scan the QR code to open the digital receipt.

A920 QR receipt screen

This option is only shown on terminals and configurations that support QR receipt.

The A920 provides two menu entry points for daily operation and advanced actions.

The transaction menu is opened through the star icon at the lower left of the terminal screen.

This menu provides quick access to common transaction-related actions such as reversal, credit, prepaid, final balance, ticket reprint, reports, print info, and order paper.

The full merchant menu is opened through the hamburger icon at the bottom right of the terminal screen.

This menu provides access to merchant functions, setup options, and operational actions.

Some flows require a merchant password before they can be executed. If you do not know the password, contact the person responsible for terminals at your company.
