Accepting Card Payments on a Device without a Headphone Jack

Some newer devices from leading phone manufacturers like Apple no longer include a headphone jack, which might change how you accept magnetic stripe-only cards. While most customers are carrying tap-and-go cards, you might still need to accept an international credit or debit card without an EMV chip.

While they don’t have a built-in port, some devices include an adaptor that enables you to connect 3.5mm audio accessories, like your favorite headphones or the Square Reader, to the device’s main port (like a USB-C port or Apple’s Lightning connector).

Below is a list of devices that don’t have a headphone jack and our recommendation for how to accept payments with them:

iPhone 7, iPhone 8 and iPhone X
These devices include a Lightning to 3.5 mm Headphone Jack adaptor, which you can connect to the Square Chip Card Reader. For better ease of use, we recommend connecting the Square contactless and chip reader wirelessly to iPhone 7.

Google Pixel, Google Pixel 2
These devices include a USB-C to 3.5 mm Digital to 3.5 mm Headphone Jack adaptor, which you can connect to the Square Chip Card reader. For more convenient connectivity, we recommend connected the Square contactless and chip reader wirelessly to Google Pixel.

If you have a new device without a headphone jack, we recommend using the Square contactless and chip reader with your new device, as it connects wirelessly with Bluetooth LE. You can also accept contactless card payments, chip card payments, and mobile wallets like Apple Pay and Google Pay.

What if the Square Chip Card Reader is incompatible with my device?
If you must accept a card that only has a magnetic stripe, you will need to manually enter the payment information. For manually entered transactions, Square’s standard 2.2% per manually entered transaction fee will be applied. We also recommend using the Square contactless and chip reader with your new device, as it connects wirelessly with Bluetooth LE. You can also accept contactless card payments, chip card payments and mobile wallets like Apple Pay and Google Pay.
