Android Device Compatibility

We work hard to support as many Android devices as possible! Supported Android devices have the following specifications:

• Google Android 5.0 or higher
• A 3.5 mm headset jack with microphone (audio jack adaptors are not supported)
• Location services enabled
• Access to Google Play

Note: If you plan to connect your Android device to supported hardware, make sure your device supports USB OTG (On-The-Go).

If your Device Doesn’t Have a Headphone Jack

We recommend using the Square contactless and chip reader for a fast, seamless payment experience on all devices – not just those without a headphone jack. To accept magstripe-only cards, or gift cards, we recommend using the Apple Lightning to Headphone Jack adaptor (included with the iPhone 7) to connect your Square magstripe reader. You might also try a third-party USB-C to 3.5 mm audio adaptor, but please note that Square has not officially tested compatibility between the magstripe reader and other third-party adaptors.
