If you have an iPhone 7 or newer, you can use the new Square Reader for Magstripe with Lightning connector. You can order a Square Reader from our Square shop and get started processing payments.
If you are using a device that does not have a headset jack, you can use the headset adapter included with your device 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).
We also recommend using the Square Reader for contactless and chip 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.
