Standalone terminals

Set up a Standalone terminal, and make transactions.

If you don't need a fully featured point of sale integration, you can use our Standalone solution instead.

This is our quickest way to start accepting in-store payments for credit cards, debit cards, Alipay, and WeChat Pay, as well as issue refunds. It does not require any development or integration work, or even a cash register system.

Instead, you initiate transactions directly from a Standalone terminal.

If you use Standalone terminals, you will not be able to use features like offline transactions, shopper recognition, or tax free shopping. You will also need to manually reconcile your point of sale transactions against your sales and returns.

Here we explain how to set up a Standalone terminal. Once you have done this, you can immediately begin making payments and issuing refunds.

Supported terminals
To use our Standalone solution, you need to use terminals with a built-in printer such as the V400m or V400c terminals.

Before you begin

Before you can make transactions using our Standalone solution you need to:

  1. Sign up for an Adyen test account.
  2. Order a test terminal. The V400m and V400c can be used as Standalone terminals. Don't forget to add an Adyen test card to your order.
  3. Determine your Adyen account structure, and create accounts for your physical stores.
  4. Add payment methods to your account.
  5. Board the terminal, and associate it with a physical store.

Once you have boarded your terminal you will need to set it up as a Standalone terminal.

Set up Standalone terminals

Before you can make transactions from your terminals, you need to set them up to operate as Standalone terminals:

  1. Log in to your Adyen Customer Area.
  2. Go to Point of sale > Terminal settings.
  3. Select Payment features and in the Terminal default currency box select a currency for standalone transactions.
  4. Select Save.
  5. Select Integrations and under Standalone:

    • Enable standalone.
    • Show or hide the Start button. When the Start button is hidden, you start a transaction by entering the amount.
    • Optional. If you want to add a unique reference to each transaction, enter your Merchant reference using text and variables.

      You can use these unique references to reconcile transactions that are recorded in your sale system.

    • Optional. If you want to show your merchant reference on the terminal display, enable Show merchant reference.

  6. Select Save.

Your terminals will reboot. After rebooting, each terminal is ready to be used as a Standalone terminal.

For refunds and MOTO transactions, it's possible to let the terminal ask your staff to manually enter a transaction reference. Contact our POS Support Team if you want to enable this.

Also contact our POS Support Team if you want to enable tipping.

Make a payment

Once you've set up your terminal, you can initiate a payment by entering the value of the transaction on the terminal, then handing it to the shopper to complete the transaction.

Standalone terminals support credit and debit cards, NFC wallets, and QR code wallets.

To make a payment with a credit or debit card or NFC wallet from a Standalone terminal:

  1. Select Start on the terminal display, or select the Confirm key on the keypad.

Making QR code payments

Standalone terminals also support wallets like Alipay and WeChat Pay. For these payment methods, a QR code is shown on the terminal display. The shopper uses the app on their phone to scan this QR code and complete the payment.

To make a QR code payment:

  1. Select Start on the terminal display, or select the Confirm key on the keypad.

    If the display doesn't show Start, you can enter the transaction value immediately.

Tipping

If our POS Support Team has enabled tipping for your account, the terminal will prompt for a tip with every payment that you initiate:

  1. Select Start on the terminal display, or select the Confirm key on the keypad.

    If the display doesn't show Start, you can enter the transaction value immediately.

  2. On the keypad, enter the transaction value and select .
    The terminal shows a message asking the shopper whether they want to add a tip.

    The terminal now asks the shopper to present their card.
  4. The shopper presents their card or their device with the NFC chip to the terminal and follows the instructions on the terminal to complete the payment.

Manually entering card details

Manual Keyed Entry (MKE) involves manually typing the details from a shopper's card into the payment terminal. You can use this when the payment terminal fails to obtain the card details from the card's chip or magnetic stripe.

The transaction then follows the normal flow.

Cancelling a payment

Before a payment has finished processing you can attempt to cancel it:

  1. On the terminal keypad, select the Cancel key .
  2. On the display of the terminal, confirm that you want to cancel the transaction.

If your cancel attempt is successful, the terminal shows a Cancelled message on the display.

If the cancel attempt failed (and the payment was Approved), you will need to issue a refund.

Issue a refund

There are two types of refund you can make from a Standalone terminal:

When possible, we recommend using referenced refunds as they offer the following advantages:

  • Lower risk of return fraud: A payment can't be refunded multiple times.
  • Lower risk of human error: Store staff cannot enter the wrong refund amount on the terminal.
  • Support for QR code payment methods, such as Alipay and WeChat Pay.

When a refund has been processed it is deducted from your in-process funds, and will appear in your shopper's account within a few days.

Make a referenced refund

Before you can make referenced refunds, contact our POS Support Team team, so they can enable referenced refunds for your Adyen account.

  1. Open the Admin menu:

    1. On the terminal keypad, select 9 and then the Confirm key . (On some models, it is Confirm and then 9.)
    2. Enter the PIN code for the Admin menu and select .
      Where do I find the Admin PIN?

  2. On the terminal display, select Transactions, then select the transaction you want to refund.
  3. Select Actions > Void transaction.

The terminal prints a receipt for the refund.

If successful, the refund is issued directly to the shopper's account.
