We can’t guarantee support with all Android devices at the moment, but we’re working to support as many as possible. If your device isn’t currently on this list, there’s a chance it will be supported in the future.

If you have any problems with your reader, you can return it within 30 days.

If your Device Doesn’t Have a Headphone Jack

The Apple Lightning to Headphone Jack adapter included with the iPhone 7 and newer is compatible with Square Magstripe Card Reader and the Square Chip and Pin Card Reader. Android Headphone Jack adapters should also work however these are not all tested.

We recommend using the Square Contactless and Chip Reader for a seamless payment experience for chip and pin cards and contactless payments, as it connects via Bluetooth Low Energy.
