Square Register does not have a browser or support any app stores. This means that you can’t 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 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.

One of the benefits of Square Register is that we keep the software up to date automatically, so you will always get the latest features and improvements with no additional cost. We will update the software 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 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 the 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 on ‘Update Available’ and instal the update right away. The process of installing an update includes a reboot and a 20-25 minute total downtime. During part of this downtime while your customer display is updating, you can still process card payments by keying in card numbers on Register, if necessary. If your business doesn’t allow you to update Register right away, Register will go through the normal update process overnight, provided it is plugged into power.

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

After your first update, you’ll be able to control your reboot time if 3 a.m. doesn’t work for your business. Tap the switcher at the top of your Register and choose Settings > Hardware > General > About Register. You can choose to install the update sooner than 3 a.m. when it might be a more convenient time for your business.

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. Updates involve a reboot of Square Register and the customer display. Updates are released approximately every 2–4 weeks. To ensure your business is not interrupted, please leave Square Register on at all times. Updates will be applied automatically overnight.
