Universal GUI barcode scanner

We are using the Univeral GUI on Android tablets for scanning barcode on products. We have noticed that often the barcode scanner has trouble to scan the barcode. 

In the Mobile GUI the scanner works better and faster, because there is a red line where you can put the barcode on the camera. 

Is there any way to improve scanning using the Universal GUI?

Hi @Zachery,

This isn't possible out-of-the-box at the moment. Instead, you could show a red box like this:

Using custom CSS like this:

.popup__content:has(video)::after {
    content: '';
    display: inline-block;
    width: 40%;
    height: 25%;
    left: 30%;
    position: relative;
    top: -62%;
    border: 3px solid red;

Kind regards,
Leroy Witteveen

Hi @Leroy Witteveen,

Got it. 
But is there any way to improve the scanning? We have noticed that scanning barcodes (linear codes) seems difficult to pick up.

Hi Zachery,

The Thinkwise platform can employ a more powerful barcode scanning library called the Cortex Decoder. This barcode scanner offers higher precision and additional symbologies.

The Cortex Decoder requires a license of the manufacturer aimed at Thinkwise applications. More information here - or contact your Thinkwise representative.
