How often does Square Terminal software update?

One of the benefits of Square Terminal is that we keep the software up to date automatically, so you’ll always get the latest features and improvements without any cost. We’ll update the software every 2–4 weeks. To enable automatic updates, you’ll just need to leave Square Terminal powered on and plugged in overnight. Automatic updates require a battery level of at least 35% to initiate.

Note: Software updates for Square Terminal generally require 2 GB per month. This doesn’t include attempts to retry failed downloads, so it’s recommended to connect to Wi-Fi overnight to help facilitate software updates.

Square Terminal software updates may include a system update, Square app updates and a firmware update.

If a Square apps update is recommended before the automatic nightly update, a notification will appear on the screen. To defer this update, tap Defer Update. The update will then begin overnight at 03:00 (or at your custom-set time) as long as your Square Terminal is powered on and plugged in. To start the update immediately, tap Install Now.

If you manually update your Square Terminal software from your settings, you will not see an option to defer the Square apps update. The update may take up to one hour to complete.

Why is my device updating in the morning?

If you’ve powered down your Square Terminal overnight and there are software updates available, you’ll be prompted to choose a software update option when you next power on your device. Updates are released approximately every 2–4 weeks, involve a reboot of Square Terminal and typically take around 20 minutes to complete, but may take up to an hour.

  • Tap Install Now to immediately start the update.
  • Tap Defer Update to delay the update by up to seven days. You’ll be prompted once a day to update until the seventh day. Then you’ll be required to update the software.
  • You can manually start the software update at any time by tapping ≡ More > Settings > Hardware > General > About Terminal > Software Update > Install Now.

Note: In some cases, updates are required immediately for security purposes and you might not see the option to Defer Update.

To ensure your Square Terminal can update overnight, just make sure it’s plugged in and powered on, but the display can be turned off. To turn off the display, simply tap the power button quickly and Square Terminal will go to sleep.

How do I know if my Square Terminal software is up to date?

You can check your software at any time. Head to ≡ More > Settings > Hardware > General. Scroll to the bottom of the page and tap About Terminal. From this page, you’ll see your software version. Tap Check for Update to see if a software update is available. If you see Software Up To Date, then you’re all set.

How can I change the time at which software updates happen?

Software updates are, by default, set at 03:00 to avoid any disruption to your normal business hours. If you need to adjust your nightly reboot time, head to ≡ More > Settings > Hardware > General from the navigation bar at the bottom of your screen. Tap Nightly Reboot and select the time that works best for your business.

Note: This adjustment won’t take effect on the next nightly reboot, but instead the one after that.

Why do some software updates take longer than others?

Square Terminal software updates may include a system update, Square app updates and a firmware update. Software updates can take anywhere from 15 minutes to one hour to complete, depending on which updates are needed.

Square Terminal does not have a browser. This means that you can’t use Square Terminal to check emails, access search engines (e.g. Google) or browse any other websites that aren’t within Square’s domain.

Can I download other apps on Square Terminal?
