Socket Mobile 2D barcode scanner

Your store needs to be on the Shopify plan or higher to use this hardware.

If you're using Shopify POS for iPad and your store is on the Shopify plan or higher, then you can use the Socket Mobile S740 or CHS 7Qi 2D barcode scanner for scanning both digital and printed 1D and 2D barcodes.

Shopify POS - Socket Mobile barcode scanner

The Socket Mobile S740 and CHS 7Qi are lightweight, portable barcode scanners that connect wirelessly to Shopify POS.

Who is the 2D barcode scanner for?

You should use the Socket Mobile S740 or CHS 7Qi 2D barcode scanner if you want to scan both 1D and 2D barcodes. You can scan 1D barcodes on products to add them to the cart quickly without browsing your catalog to find them. You can scan 2D barcodes on receipts to quickly find the order associated with that sale.

The scanner connects wirelessly to Shopify POS with Bluetooth, so you can use it at markets, fairs, pop-up locations, or a physical store. It's charged by the included charging cable or charging cradle, both of which need to be plugged in to a power socket. When fully charged, the scanner's battery will last for up to 14 hours (about 15,000 scans).

This short video shows you how to set up and use your barcode scanner with an iPad:


  1. Go to your iPad settings (not the app settings) and make sure that Bluetooth is turned on.

  2. In the Shopify POS app, go to the Settings screen.

  3. Tap Hardware to access the hardware settings.

  4. Turn on the barcode scanner by holding down the power button until the scanner beeps.

  5. On the iPad, tap Add bluetooth barcode scanner:

    Add bluetooth barcode scanner button

  6. When the Pair and Connect Scanner dialog appears, tap 2D Scanner, then scan the barcode. The scanner will beep three times, indicating that the scanner and the iPad are now paired:

  7. Tap Open Device List.

  8. To connect the barcode scanner, tap it when it appears in the list (you might have to wait a few moments).

When the connection is successful, you'll see a message on your Hardware settings screen, and the Bluetooth Barcode Scanner will show as connected:

If the setup is not successful, then unpair the scanner and try again.

As long as the scanner remains paired with the iPad, it will connect automatically whenever it's in range.

Pairing with another iPad or a different Bluetooth device

You can pair your scanner with another iPad or Bluetooth device.


  1. Unpair the barcode scanner.

  2. Pair your scanner with another iPad, or read the manufacturer's instructions to pair with a different Bluetooth device. Make sure that Bluetooth is enabled on the new device.

Unpair your barcode scanner

By default, your barcode scanner will try to connect to the last device it was paired with. If you want to use your barcode scanner with a different Bluetooth device, then you'll need to unpair the scanner first.


  1. Turn on your barcode scanner.

  2. Press and hold the scan button. At the same time, press and hold the Power button. When you hear three beeps, release both buttons. Your barcode scanner will power off.

  3. In Shopify POS, tap Store, and then tap Hardware.

  4. Make sure that the barcode scanner is not paired. If it is, then swipe it left, and tap Delete.

  5. Go to your iPad's Settings app.

  6. Tap Bluetooth.

  7. Under MY DEVICES, tap the button beside the Socket barcode scanner:

    Shopify POS - 2D barcode scanner settings

  8. Tap Forget This Device.

  9. Tap OK.


If you're having trouble scanning barcodes with Shopify POS and the Socket Mobile S740 or CHS 7Qi barcode scanner, then try these troubleshooting steps to fix the problem:

Check your scanner setup

  1. Are you using the correct barcode scanner? The only 2D barcode scanners that Shopify POS supports are the Socket Mobile S740 and CHS 7Qi.

  2. Are you using the barcode scanner with an iPad? The barcode scanner doesn't work with Shopify POS for iPhone or Android.

  3. Is the store that you're logged in with on the Shopify plan or higher? Your store needs to be on the Shopify plan or higher for you to use additional hardware with Shopify POS.

  4. Is the scanner charged and in range of the iPad? Check that the scanner is fully charged and within range (100 meters or less).

  5. What type of barcode are you scanning? Make sure that you're using a supported barcode type.

Check that your scanner and iPad are paired correctly

  1. Is the barcode scanner showing as Connected on the Shopify POS Hardware settings screen when the scanner is on and in range? If not, then go to your iPad's Bluetooth settings and forget the barcode scanner, and pair it with your iPad again.

  2. Is the scanner showing in your iPad's Bluetooth settings? Make sure that the iPad's Bluetooth is enabled and the scanner shows as Connected.

  3. When you paired the scanner and iPad, did you scan the correct barcode in Shopify POS? The 2D barcode sets the barcode scanner to iOS mode to work with your iPad. If you didn't hear the three beeps when you scanned the barcode, or if you accidentally scanned the 1D barcode, then the scanner won't be in iOS mode. Unpair it and the iPad, and then pair them again, making sure that you scan the 2D barcode in Shopify POS and hear the three beeps before you move on to the next step.

  4. Was the scanner paired with another iPad? The scanner can be paired with only one iPad at a time. Unpair the scanner and the other iPad, and then pair the scanner with the new iPad.

  5. Do you have a poor Bluetooth connection? Read Apple's advice on reducing Bluetooth interference.

Check your products' barcodes

  1. Does the scanner recognize any barcodes? Try scanning the barcode of a nearby item that isn't one of your store's products. If your scanner is paired correctly, then you should see an Unrecognized barcode error in Shopify POS. If you see this error, then carry on to the next steps. If you don't see an error, then unpair the scanner and iPad, and pair them again.

  2. Is the product available on Shopify POS? If the product's hidden on Shopify POS, then scanning its barcode won't work because the app didn't load the product. If you see an Unrecognized barcode error, then check the product's availability settings in your Shopify admin.

  3. Does the barcode number on the label match the product's barcode number in your Shopify admin? If there are extra zeros at the beginning or end of the number, then delete them and try again.

Trying to scan in inventory with the barcode scanner?

You can't scan in inventory with Shopify POS. The barcode scanner is for quickly adding products to the cart before checkout.
