Devices running an updated version of the Square app: Version five or later for iOS. Learn how to update your Square app.
Devices enabled with Bluetooth Low Energy (BLE).
Check if your device is supported from Square’s Device Compatibility page.
Most Apple iOS devices running the latest iOS version are compatible.
If you’re using Square Stand, you can connect the Square Reader to your stand’s USB hardware hub to accept any payment type. Mobile devices not connected to Square Stand will connect wirelessly via BLE with the Square Reader.
If all three USB ports on the hub are occupied by other hardware, you’ll need to free up a port to plug in the card reader, as Square doesn’t support third-party USB splitters.
Some iPads do not support iOS 15 and the latest version of Apple’s mobile operating system. We recommend upgrading your hardware to get the most of the Square app. If you are using iOS 14 or earlier, you will not be able to connect wirelessly with the card reader.

Square Reader is supported on most Android devices with the following:
Devices must be running Android 7 or higher.

Note: Samsung Galaxy S9 is not compatible with Square Reader (2nd generation).
