Hi there!
To help find the best solution, could you clarify how you’re creating the barcode numbers for the new products? For example:
- Are you entering them manually, or using a plugin to generate them?
- Are the old products using a different barcode field or format than the new ones?
Knowing this will help me recommend a stable plugin or solution that restores the scanner functionality.
Also, do the old products (where scanning works) use a different barcode format or field than the new products? This will help us identify why the scanner isn’t adding new products to the cart.
One option you could consider is that the WooCommerce Mobile App supports barcode scanning when using the Point of Sale (POS) mode. Barcode scanning allows you to connect a supported external barcode scanner to scan products supported barcodes and automatically add the product to the Cart when in POS mode.
For more details you can use this guide.

I hope this helps.
Hi,
I was using the mobile app and it works fine on the first 120+ items. Then all the sudden when I make a new on it it doesn’t find the new items, but still works fine on the old numbers. That is why I was asking about a plugin. I’d also like, if possible to be able to print a receipt.
Hi there!
Thanks for the clarification that makes sense. I understand the mobile app worked for your older products, but now it’s not detecting newly created items, and you’d like the ability to scan products and print a receipt. That’s a valid need, especially if you’re scanning lots of items regularly.
You can try the following plugin as a starting point:
👉 Barcode Scanner & POS – Inventory and Orders
https://ww.wp.xz.cn/plugins/barcode-scanner-lite-pos-to-manage-products-inventory-and-orders/
This plugin has good reviews and is designed to let you scan barcodes and manage products/orders. While we haven’t personally tested it, many users find it helpful for basic barcode scanning workflows, and it may help with your scanning needs.
If this plugin doesn’t fully meet your needs (for example, if you need built-in receipt printing or a more robust point-of-sale experience), you’re free to choose any other plugin that works best for your setup. There are several POS plugins available that support both barcode scanning and receipt printing, depending on how advanced you need the system to be.
It seems we haven’t heard back from you for a while, so I’ll go ahead and mark this thread as resolved. Feel free to reach out whenever you’re ready to continue.
If you have time, we’d be grateful for a review: https://ww.wp.xz.cn/support/plugin/woocommerce/reviews/
If it worked for your first 120+ products but not new ones, it’s usually not the scanner itself, it’s how the barcode is stored.
Common causes:
- barcode/GTIN missing on new products
- stored in a different meta field than older products
- duplicate barcodes
- assigning the same barcode to multiple variations (this is quite common and can break product lookup)
Scanning relies on a 1:1 match, so if multiple products/variations share the same code, or the field isn’t consistent, the system won’t know what to return.
For a setup like yours, a proper barcode workflow should:
- ensure each product/variation has a unique barcode
- keep barcode data in a consistent field
- prevent duplicates
- support fast lookup for POS/cart
- ideally include label printing
This page outlines those basics and what to watch for:

Once that’s cleaned up, scanning should start working reliably again regardless of the app/plugin used.
Hi @donlee101,
Thanks for taking the time to share that detailed explanation, it is really helpful and adds valuable context to the discussion. Your breakdown of how barcode data consistency and uniqueness affect scanning reliability is spot on, and I am confident it will help others facing similar issues better understand what to look out for.
We truly appreciate your contribution to the community 🙌
