Using a bar code scanner in .NET. Download demo - 8.92 KB Introduction The vast majority of bar code scanners emulate keyboards which allows them to be easily used in any application. The user simply needs to put the focus on any text input control and then scan a bar code. This same behaviour though also allows the user to scan bar codes into fields not intended for scanning, and does not allow the application to take instant action when a scan is received because the application has no way of distinguishing the bar code scanner input from the keyboard. Many vendors have their own APIs which can be used to distinguish the bar code scanner from the keyboard, but in the real world, there are thousands of bar code scanners and relying on vendor specific APIs is not practical.
Fortunately, there is an easy yet not well known method for detecting distinct input from the bar code scanner.

Simply put, POS for .NET enables developers to utilize receipt printers, cash drawers, barcode scanners, magnetic stripe readers (MSR), line displays (and many other peripherals) within their .NET applications.
Back then, the .NET framework was at version 2.0. Obviously, many things have changed since then with the advent of .NET 3.0, 3.5 and, more recently, 4.0. However, the latest version of POS for .NET’s is v1.12 and it was released in 2008. Being forward-thinking as we are, we structured our point of sale as a web application from day one, to enable future deployment scenarios (being browser-based means we can easily use our point of sale on the iPad or any other hot hardware platform) and code-reuse within our e-commerce application and FranchiseBlast.
