One of the benefits of Square Terminal is that we keep the software up to date automatically, so you will always get the latest features and improvements without any cost. We will 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 does not include attempts to retry failed downloads, so it is recommended to connect to WiFi overnight to help facilitate software updates.
Square Terminal software includes a system update, Square apps update, 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 Update Tonight. The update will then begin overnight at 3 a.m. (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 45 minutes to complete.
