To scan barcodes from the LCD and LED screen or mobile phones such as the iPhone or Android, it is suggested to use a laser-like performance CCD-based barcode scanner, such as the IDAutomation USB Scanner or the camera-based IDAutomation 2D Scanner should be used. These scanners provide the capability to read barcodes from LCD & LED monitors provided the barcode is created at the proper resolution to match the screen. Scanning from the screen may also be used to easily and securely transfer and reformat the text from one web application to another with the QR-Code or Data Matrix barcode types.

1. The following web based barcode generation components easily create barcodes at the proper resolution of the screen by default:
   1. ASP Barcode Server for IIS
   2. Online Barcode Creator
   3. Free QR-Code Barcode Generator
   4. Dynamic Barcode Generator Service
   5. ASP.NET Server Control
   6. Java Barcode Servlet
2. Plug the IDAutomation 2D Scanner or the IDAutomation SC5 Scanner into an available USB port. The IDAutomation 2D Scanner will decode barcodes from the screen quicker because it takes a picture of the screen and decodes it in memory, as seen in this video.
3. Open a text editor or word processor and scan the barcode. The data scanned will appear at the cursor as if it was typed from the keyboard.
4. This video demonstrates the transfer of data from one web application to another without the security concerns of actually transmitting the data over the wire. The video uses the Free QR-Code Barcode Generator on a mobile phone and a flat-screen PC monitor.
