Continuous Scans

Hello everyone,

 

I am making an attendance app where I need to scan students' badges. With the new barcode scanner, I am not able to find a way where I can keep scanning badges continuously without user interaction after initial press on the scan button. Is there a way to accomplish this? 

 

Thank you in advance.

Re: Continuous Scans

Hi @BigTex ,

Could you please share a bit more about your scenario?

Do you want to keep scanning badges continuously without user interaction after initial press on the scan button?

 

Based on the needs that you mentioned, I have made a test on my side, please take a try with the following workaround:

Set the OnScan property of the Barcode Scanner control (BarcodeScanner1) in your app to following:

Select(BarcodeScanner1)  /* <-- Auto fire the Barcode scanner without interaction after initial press on the scan button */

 

In addition, I also think the older version Web Barcode scanner could also achieve your needs. You could consider enable the "Web barcode scanner" option within Advanced settings of App settings of your app, then you could use the "Web barcode scanner" control in your app as below:

The Web barcode scanner would keep scanning badges continuously without user interaction.

Re: Continuous Scans

It sounds like what you want is for the scanner to scan a new badge when it senses that the code has changed.  I don't think that's possible.  You have to use a button to have the scanner take a picture and then analyze it.

Spoiler

This worked for me. It scans and then auto fires the scanner again.

Set the OnScan property of the Barcode Scanner control (BarcodeScanner1) in your app to following:

Select(BarcodeScanner1)  /* <-- Auto fire the Barcode scanner without interaction after initial press on the scan button */

You have to select the scanner on the OnScan property. Select(BarcodeScanner1); and not just (BarcodeScanner1). It works perfectly fine for me without freezing.

It's solved!

I had placed the camera and barcode on the same form.(Both functions are necessary for me.)

When I delete camera function, Select(BarcodeScanner1)work peerfectly!

Thank you very much.
