Bar code scanner

Topic summary

Main issue: A two-year-old barcode scanner stopped functioning even after battery replacement and repeated re-pairing with Shopify POS.

  • Symptoms: Scanner won’t scan, can’t be powered off, shows a flashing red light; cradle light appears normal. Lights reportedly stay on even when batteries are removed.
  • Steps tried: Replaced rechargeable batteries; removed and re-added the scanner in Shopify multiple times; no improvement.
  • Context: Another user reported experiencing a similar issue and asked if a fix was found.

Community guidance:

  • One participant explained scanners act like keyboards, often sending an ENTER keystroke after the code. Misconfiguration (e.g., ENTER remapped) can cause “reads but no submit.”
  • Suggested actions: Check the model’s manual for configuration barcodes, verify connection type (Bluetooth vs. wired), barcode type (QR vs. linear), and the target input app. Requested detailed device info for better troubleshooting.

Outcome/status:

  • Original poster ultimately purchased a replacement scanner and expressed dissatisfaction with Shopify support.
  • No confirmed technical resolution was provided; the root cause remains unclear, and the issue appears unresolved for others.

I have replaced the rechargeable batteries but the scanner is not working. I have to keep taking it out of the system and adding it back.

As in when you scan nothing happens at all? Think of Barcode scanners as fancy keyboards where usually what they’re doing ‘under the hood’ is quickly typing all the ‘keys’ read from the barcode and hitting ENTER. How these scanners are configured are ironically enough, usually scanning certain settings in the manual. One common issue we see is it reads the barcode but does not submit, because that ENTER has been swapped to a different key. You could look in the manual or online for the specific model and see what people are saying. For additional troubleshooting it would be helpful if you:

Explain what’s happening in more detail (is it just not turning on?), Provided the model of scanner, bluetooth or wired, scanning QR codes or regular Barcodes, where you’re trying to scan the code into, etc.

People are generally going to have a hard time helping with a hardware issue.

The bar code scanner is two years old. I replaced the rechargeable batteries thinking g it was the problem. I can’t even turn the scanner off. There is a red light flashing and the cradle has the appropriate light on. I’ve gone into Shopify and deleted the scanner and then added it back. I have tried everything but it won’t scan and the lights won’t turn off even when removing the batteries.
It’s a disaster in the shop with this device. How can you help me.

I am having a similar issue. Did you get a resolution?

I was forced to buy another. I am not happy with Shopify or their customer service, which is non existent. Am looking to change to another system.
