How to read a barcode from the LCD monitor screen with a Barcode Scanner

To scan barcodes from the LCD monitor screen, a camera based scanner (often referred to as a linear imager) must be used, such as the IDAutomation Plug 'n Play USB Barcode Scanner. This scanner has the capability to read barcodes from an LCD monitor provided the barcode is created at the proper resolution to match the screen, which is usually 96dpi. Scanning from the screen may be used to easily transfer and reformat text from one web application to another.

1. The following web based barcode generation components easily create barcodes at the proper resolution of the screen by default:

• ASP Barcode Server for IIS
• Free Online Barcode Creator
• Dynamic Barcode Generator Service
• ASP.NET Server Control
• Java Barcode Servlet

2. Plug the IDAutomation USB Barcode Scanner into an available USB port.
3. Open a text editor window, such as Notepad, and place it on top of the window with the barcode. When the barcode is scanned, the data should appear in Notepad as in the example below.
