I have am building a win forms app which will have a text box that needs to be populated with a unique Id from an RFID tag.
The reader is recognized by windows as a keyboard device and when a tag is scanned the uid is written as If typed from a keyboard.
I need to ensure that a single textbox in my app can only take input from the RFID reader “keyboard”
Is this even possible?
You should not do this. if the reader is unable to scan or broken the operator will read the digits and type them in with the standard keyboard, like they do at the store when you buy something and label is not readable because twisted or so…
