Square Register does not have a browser or support any app stores. This means that you cannot use Square Register to check emails, access search engines (e.g. Google) or browse any other websites that are not within Square’s domain. You also are not able to download third-party apps onto your Square Register.

Square Register has a hub that allows up to 5 USB devices. Currently, receipt/kitchen printers, barcode scanners, keyboards, scales and cash drawers are supported. Bluetooth-connected hardware accessories are not supported at this time. Please check the exact models supported by Square Register.

When cleaning the outside of your Register, first shut down your Register and unplug the power adapter. Then use a damp, soft, lint-free cloth to clean the exterior of the Register. Avoid getting moisture in any openings. Do not spray liquid directly on the Register. Don’t use aerosol sprays, solvents, abrasives or cleaners containing hydrogen peroxide that might damage the finish.

To clean the screen on your Register, first shut down the device and unplug the power adapter. Dampen a soft, lint-free cloth with water only, then use it to clean the Register screen.

If you tap Notifications, you will be able to see the details of each notification. They are important messages for you to know. If there are more actions to be done, you should be able to tap on a message to get directed to an appropriate page.

Unless you perform the action requested by each message, that notification will not go away.

The Square Register software updates automatically overnight as long as the device is plugged in and powered on. We update the software every 2–4 weeks.

A Square Register software update 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 at 3:00 (or at your custom set time) as long as your Square Register is powered on and plugged in. To start the update immediately, tap Install Now.

If you manually update your Register 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.

If you’ve powered down your Square Register overnight and there is a software update available, the update will be applied when you next power on your device. For updates to apply and complete automatically, keep your Square Register plugged in and powered on overnight. Updates involve a reboot of Square Register and the customer display and are released approximately every 2–4 weeks.

You can go to Settings > Hardware > General > About Register to check if your software version is up to date. We release software for Square Register every 2–4 weeks and Square Register checks for availability of updates every 15 minutes. For more details on the latest software update, check out our Seller Community.

Software update requires network connection and power, so make sure that Square Register is connected to a network via Wi-Fi/Ethernet and powered on, even when not in use. When you’re not using Square Register, you can dim the screens simply by pressing and quickly releasing the power button.

Most software updates should happen automatically every 2–4 weeks. However, sometimes we have a critical update that should be installed more urgently. You can tap Update Available and install the update right away. The process of installing an update includes a reboot. Updates typically take around 20 minutes to complete but may take up to one hour. While your customer display is updating, you can still process card payments by keying in card numbers on Square Register, if necessary. If your business doesn’t allow you to update Square Register straight away, Square Register will go through the normal update process overnight if it is plugged in and powered on.

Currently, software updates happen during the nightly reboot time, which is set at 3:00 in your time zone to avoid usual business hours. If your business is open at 3:00, the software update process will prevent you from taking payments for 10–15 minutes while the customer display software updates.

After your first update, you can adjust your reboot time if 3:00 does not work for your business. Tap the switcher at the top of your Square Register and choose Settings > Hardware > General > Nightly Reboot. You can then choose to install the update at a more convenient time for your business.
