Who is this card reader for?

The Swipe (audio-jack) card reader is lightweight and low-cost, which makes it a good option for merchants who are just getting started with taking credit card payments. The card reader plugs into the audio jack of your POS device and has no wires, so it's ideal for use at fairs, markets, or pop-up locations.

Compatible devices and payment providers

The Swipe (audio-jack) card reader processes payments through Shopify Payments in the United States and Canada.

The Shopify POS app works with devices which meet the following requirements:

iOS 14 permission requirements

If you have updated your device to iOS 14 or higher and use third-party Shopify apps, then you might need to enable Cross-Website tracking in your iOS settings.

To enable Cross-Website tracking, complete the following steps:

  1. Open the Settings app on your device.
  2. Tap Shopify, Shopify POS, or Shopify Inbox.
  3. Enable Allow Cross-Website Tracking.

If you see a Swipe failed error when you swipe a card, then make sure that you're swiping the card correctly.

2. Do you have an internet connection?

To process payments, Shopify POS needs to connect to the internet through Wi-Fi or your device's cellular data. If you can't connect to the internet, then you can't process card payments.

3. Are you using a compatible payment provider and currency?

You can use the Swipe (audio-jack) card reader only if:

If one of those requirements isn't true for you, then you can still take credit card payments using an external payment terminal.

4. Are you tapping Credit at checkout?

To accept payment with the Swipe (audio-jack) card reader, tap Credit at the payments screen. You should tap External terminal only if you're using an external payment terminal instead of a card reader that's supported by Shopify.

5. Is your POS device in a case?

Some cases prevent the Swipe (audio-jack) card reader from fitting properly in the device's audio jack. If your device is in a case, then remove your device from its case, plug in the card reader, and try processing the payment again.

6. Is your device being used to play music?

The Swipe (audio-jack) card reader uses your device's audio framework, and so you can't use your POS device to play music and to accept credit card payments at the same time. If you want to take a card payment, then disconnect your POS device from any Bluetooth speakers, check that the device has microphone permissions, and then try taking the payment again.

7. Does Shopify POS have permission to use your device's microphone

Shopify POS needs permission to use your device's microphone to use the Swipe (audio-jack) card reader to take credit payments. If you declined giving the app permission, then you can grant it from your device settings.

Steps:

  1. On your device's home screen, tap Settings.

  2. From your device's Settings screen, find the Shopify POS app, and then tap it.

  3. Under ALLOW SHOPIFY POS TO ACCESS, make sure that the Microphone toggle button is enabled.

8. Is the volume on your device at maximum?

Shopify POS won't recognize the Swipe (audio-jack) card reader unless your device is unmuted and its volume is at its maximum. Unplug the card reader, make sure that your device isn't muted and the volume is at its maximum, and then plug in the card reader and try to take the payment again.

9. Have you disabled the Automatically detect swipe reader option (iOS only)?

You might have disabled the Automatically detect swipe reader setting in Shopify POS, for example if you wanted to use the device to play music. You need to enable the Automatically detect swipe reader setting.

Steps:

  1. From Shopify POS, tap , and then tap Manage connected hardware.

  2. Enable Automatically detect swipe reader.

10. Can you take a credit payment using a different card?

Try to take a card payment using a different credit card. If the payment is successful, then there is a problem with your customer's credit card.

11. Can you process the payment by entering the credit card information manually?

Try to take the card payment by entering the card information manually. If the payment is successful, then there's a problem with the card reader.
