Card reader

Learn how to set up and use the card reader.

Our mobile integration solution is in the development phase. The documentation will change as the solution evolves. If you have any feedback about the card reader, reach out to your Adyen contact.

In a mobile integration you can use the secure card reader to accept payments that you start from a mobile POS app on your phone or other mobile device. The mobile device and the card reader communicate with each other through Bluetooth.

To indicate the progress of the payment and other events, the reader has indicator LEDs, an illuminating contactless logo, and a dual-tone buzzer. Transaction screens appear on the mobile device that is paired with the reader.

Supplied components

  • BlueLite card reader
  • USB cable

A charger is not included.
Use a 5V DC, 1A charger to recharge the battery. The battery can't be replaced.

Get started

  1. Inspect the card reader.
  2. Connect the card reader to a power source using the supplied USB cable.
    Let the battery charge for at least an hour and a half while you continue with the next steps.
  3. Use Bluetooth pairing to connect the card reader with a phone.

When you have completed these steps, you are ready to make transactions.

Inspect the card reader

Because card readers process sensitive card data, you must verify that the reader you received is the correct one, supplied by Adyen, and hasn't been tampered with.

  1. Verify that the box containing the reader hasn't been opened and that the security seal is intact.
    The security seal is a red label with a bar code and a number, stuck across the lid of the box.
  2. If you have access to the Adyen Customer Area, log in and under Point of sale > Orders and returns find the order for your reader. Then:
    • Verify that the serial number (S/N) on the box is the same as in the Customer Area.
    • Verify that the security seal number on the box is the same as in the Customer Area.
    • Using the track & trace link, track the order with the carrier to verify that they confirm having delivered the payment terminal.
  3. Break the security seal, take the reader out of the box, and verify that the serial number (S/N) on the reader is the same as the serial number on the box.
  4. Inspect the reader for tampering. Check for missing seals or screws, additional wires or labels, holes in the device, and anything inserted in or attached to any part of the reader.
If any of the above checks fails, contact our POS Support Team immediately.

Pair the reader

Where we say phone we refer to the mobile device you accept payments with: iPhone, iPad, or iPod.

To process transactions, the card reader needs to communicate with a POS app that is installed on your phone. Bluetooth technology makes this possible. First you set up a Bluetooth pairing between the card reader and your phone, as described below. After that, whenever you start a transaction, the two paired devices automatically establish an ad hoc Bluetooth connection that allows them to communicate directly.

To set up a Bluetooth pairing:

  1. On your phone, make sure Bluetooth is turned on.

  2. Open the cash register app.

  3. Select the option to connect a card reader.
    For example, the app may show Settings > Card Readers > Connect your first reader.

  4. Connect the card reader in one of the following ways:

    Option 1: Select from a list on the phone

    1. Select Select from list.
      The list shows the card readers that are within range of the phone, sorted by proximity: the reader that is nearest to the phone is shown first.
    2. From the list, select the card reader you want to use.

    Option 2: Scan the barcode using the phone's camera

    1. Select Scan barcode.
    2. If a permissions dialog appears, select the option to let the app use the phone's camera.
    3. Point the camera at the back of the phone to the barcode at the back of the card reader.

  5. When a pairing dialog appears, select the option to pair the devices. Because the card reader doesn't have a display, you can disregard the prompt to check the pairing code.

  6. On the card reader, press and hold the pairing button until a high beep sounds.
    The pairing button is a small round button without markings. It is located on the top side of the reader, together with the USB port and the power button.

  7. When the phone shows Pairing successful, select Continue.

Pair more card readers

It is possible to pair several card readers to the same phone. The steps are the same as for pairing the first card reader.

When the maximum number of paired readers has been reached, a new pair replaces the first pair.

To switch between paired readers, go to the list of readers and select one from the list. For example, the app may show the list under Settings > Card Readers.

Unpair a card reader

To unpair a card reader, go to the Bluetooth settings of the phone (or other mobile device) you are using, and select Forget this device.

Make transactions

The general process is:

  1. Make sure the phone (or other mobile device) and the card reader you want to use have been paired.

  2. On the phone, start the transaction from your mobile POS app.
    Screens related to the transaction appear on the phone.

  3. Present the card reader to the customer, to complete the transaction.
    The customer can tap, insert, or swipe their card, or use a digital wallet like Apple Pay.

  4. When the transaction is completed, use the receipt data in the Terminal API response to send the receipt to the customer, or to print the receipt on an external printer.

Manage battery power

The card reader runs on a rechargeable battery, and is on continuously. The power button on the reader serves to switch operation modes, and doesn't turn off the reader.

Check charge level

To check the battery charge level of a card reader:

  1. On the phone, go to the list of card readers.
    For example, the app may show the list under Settings > Card readers.
  2. From the list, select the card reader to see its details, including the charge level.

Charge the battery

To charge the battery of the card reader, use the original USB cable to connect the reader to a power source.

A charger is not included.
Use a 5V DC, 1A charger to recharge the battery. The battery can't be replaced.
