Keyboard wedges are great because they work everywhere without additional drivers. The problem I have with them is, you essentially combine two input channels - keyboard and RFID reader - into one, meaning at some point you invariably end up “typing” your UID into a Word document or a chat channel.
I prefer using a separate channel for the reader, and Rohos Logon Key. It’s less ubiquitous or easy because you need a compatible reader, and you need do install stuff. But once it’s setup right, you don’t need to type anything: just scan and you log in. And it won’t type garbage in your current window if you scan when you shouldn’t.
