Hello guys, I want to ask the experts here, if what technology of .NET would I consider when my client wants his POS connected to a USB-based Scanner? Is still a serial communication? I'm a new programmer so please do give me some advice. thanks

Can you be more specific as to the client's requirements? By POS do you mean "Point Of Sale" or are you referring to a "Piece Of S**t" computer? You won't find a scanner these days that uses the old serial port - just USB. Pretty much all scanners come with software so without knkowing details as to how it will be used it is hard to offer an opinion.

POS computer made me laugh

They want to connect their scanner to the POS system. I need some tutorials on how to do that.


the scanners I have used simulate keyboard entry. That is, what is scanned appears as if the user has typed it on the keyboard. set focus on a textbox then scan and the data from the scanner will be placed in the text box. it is usually terminated with a CR so place some code in the Lost_Focus event to handle the data.
