Troubleshoot Bluetooth barcode scanners
-
If you're using a Bluetooth scanner, confirm you’re using a compatible Apple device such as an iPad or iPhone.
Bluetooth scanners do not work with Square Register, Square Terminal or Android devices.
Check that your scanner is fully charged.
Make sure the scanner is paired to your iOS device and not to another device.
Check that Bluetooth is turned on within your iOS settings. If enabled, turn it off and back on.

Troubleshoot USB Barcode Scanners
Check the USB connections of your barcode scanner by unplugging it from your Android or iOS device and plugging it back in.
If you are using Android, ensure your device is version 5.0 and above.
Make sure your Square Register, Square Stand or Square Terminal is plugged into the USB hardware hub, and the hub is plugged into a power adapter. Ensure the power adapter is plugged into an outlet.
Clear the USB accessory port of debris and dust.
Plug the barcode scanner into a different port on the USB hardware hub.
If you’re using a barcode scanner with your iPad and Square Stand, find additional troubleshooting tips for USB hardware.
Note: If you are having trouble pulling up your onscreen keyboard, double-click the power button on the scanner.
Reset your USB Barcode Scanner
To reset your USB barcode scanner:
Print the Quick Start Guide.
Under SET DEFAULTS, scan the barcode labelled RETURN TO FACTORY DEFAULTS while your barcode scanner is connected to your device.
Unplug the barcode scanner and then plug it back into your device.
It’s important to note that you’ll need to print the document, as you can’t scan it from your monitor or screen. Additionally, a copy of this document should’ve been included in the original scanner package.
Option 3: Troubleshoot an Android camera barcode scanner
Android devices support a built-in camera barcode scanner that uses your device's camera and volume key to scan barcodes. If the camera scanner isn't working, follow these steps:
Confirm camera barcode scanner is enabled. From the Square app, go to More > Settings > Hardware > Camera Barcode Scanner and make sure the toggle is turned on.
Verify that the Square POS app has camera permissions granted. The app will request permission to use the camera if permission hasn’t been granted when trying to scan a barcode.
Confirm that there’s a green barcode icon in the status bar of your device. This confirms barcode scanning is supported on your device.
Ensure adequate lighting and confirm the barcode is not damaged, blurry or obstructed.
Check that the volume key trigger is working. Press the volume key on your device to activate the camera scanner. If nothing happens, restart the Square app.
If the camera doesn't activate when you press the volume key, close and reopen the Square app.
If the issue persists, restart your Android device and try again.
