Standalone terminals

Set up a Standalone terminal, and make transactions.

If you don't need a fully featured point of sale integration, you may wish to 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. Both models come with an Adyen test card.
  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, and go to Point of sale > Global properties.
  2. Select the Settings tab.
  3. Set Standalone enabled to Yes.
  4. Set Standalone currency to the currency you use for transactions.
  5. Optional: If you want to display a unique transaction reference on your terminals after each transaction:

    • Set Show merchant reference to Yes.
    • For Merchant reference, specify the information you want included in your reference.

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

  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.

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 press .
  2. On the terminal keypad, enter the transaction value and press .
  3. Hand the terminal to the shopper, so they can complete the payment.
  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.

If the payment is successful, Approved is displayed on the terminal screen. The terminal also prints a receipt for the transaction.

You can find the details of the payment in your Customer Area, under Transactions > Payments.

Making QR code payments

Standalone terminals also support wallets like Alipay and WeChat Pay. For these payment methods, a QR code is presented on the terminal screen. 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 press .
  2. On the terminal keypad, enter the transaction value and press .

  5. The shopper scans the QR code on the terminal to complete the payment.

If the payment is successful, Approved is displayed on the terminal screen. The terminal also prints a receipt for the transaction.

Cancelling a payment

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

  1. Press the . button on the terminal keypad.
  2. On the terminal screen, confirm that you want to cancel the transaction.

If your cancel attempt is successful, the terminal displays a Cancelled message on the screen.

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.

  1. On the terminal keypad, press 9 + .
  2. Enter your Admin PIN and press .
  3. On the terminal screen, select Transactions, then select the transaction you want to refund.
  4. Select Actions > Void transaction.

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

  1. On the terminal keypad, press 8 + .
  2. Enter your Admin PIN and press .
  3. On the terminal screen, select Refund.
