I use a fast user switching setup posted by RickH ages ago, with RFID tags. Part of the function involves using the NumberpadValue.
Scanning an RFID tag it matches to a User PIN and logs on the correct user, logging the current one off.
However, on our latest location we have inherited some tills that use 13.56MHz RFID readers, which typically have an alphanumeric RFID code.
This isn’t a problem when logging on initially as an RFID tag of, say, EA425F60 will read as 42560, and log in the user with that PIN.
However when already logged in, the NumberpadValue is set as the full string, so it appears not to be a valid user ID. Is there any way to have any alpha characters disregarded on number pad entry?
Hope this makes sense, if not, I will try to clarify!
