RFID Question
I'm not sure if this is an RFID issue or the logic of Basic Stamp, but I was wondering if it was possible to have the RFID reader simultaneously work with other sensors. The RFID waits for a tag to be read. While it is waiting, you can not perform any other functions. Are there any solutions besides having a separate system for the RFID reader.

Others options would be to use a timeout on the SERIN for the RFID Reader to allow the BASIC Stamp to periodically check other sensors. Another option which I have tested is to use the output of the RFID to detect a transition while monitoring other sensors and then jump to the SERIN when activity has been detected. This sometimes requires the RFID Tag to be held in place for 1 second longer, but it works and you can easily indicate when a successful tag read has occurred to allow the user to remove their tag. I hope this helps. Take care.
