Connect and Manage Hardware with the Square App

Connecting hardware with the Square Point of Sale app is made easy using Square’s status bar and hardware hub – a centralised in-app system where you can: 

  • View which Square or third-party hardware is connected to your device. 

  • Set up new hardware. 

  • Configure existing hardware.

  • View detailed information for each connected hardware.  

You have a quick overview of actions that need attention, so you can keep business going seamlessly. 

The status bar will provide live alerts or connectivity issues regarding your Square hardware or third-party accessories. Tapping on the status bar will allow you to easily connect and manage your settings on a mobile device, iPad or Android tablet. 

Note: This feature is not yet available on Square Terminal or Square Register.
