Barcodes are difficult to scan – Gookit

The barcode you generate may encounter the following problems:

Difficult-to-scan barcodes or no response.

Not recognized by Wix owner app.

Difficult-to-scan barcodes or no response

Let's say we have two barcode images with the same barcode value, as shown below. The first one is hard to scan or doesn't respond, while the second can be scanned without any issues.

The root cause can be:

The barcode algorithm does not have enough space to generate clear and scannable barcodes.

The barcode is too blurry due to the printer's low DPI, making it difficult for the scanner to distinguish.

Solutions

Please adjust the width of the barcode image to maximize available space. In most cases, longer barcode values require increased width for improved readability.

To get a higher DPI printers.

If the label space is not enough, consider using a shorter SKU value for barcodes.

Not recognized by Wix owner app

This issue involves four possible scenarios:

The product with this barcode value is not in the database.

For instance, if you are using CUSTOM_BARCODE for the 'Link to' field, as shown in the image below, but the corresponding value does not exist in your database, the Wix owner app will not be able to find the associated data.

The product with this barcode value has yet to sync to the device.

The most common issue occurs when the device is offline or experiencing unstable network conditions. In such cases, the SKU data updates in the Wix catalog page may not be reflected on the device. As a result, when you scan, the app cannot find the corresponding data.

The option Show in Point of Sale has not been enabled.

Solutions

For issue 1, please ensure that the SKU data specified in the barcode is present in the Wix catalog. After scanning the barcode to retrieve its value, use that value to search on the Wix catalog page to confirm its existence in the database.

For issue 2,

Ensure that the internet is connected.

Swipe the app to close it, then reopen it to force the data update.

For issue 3, please enable the option Show in Point of Sale.
