Our readers do not have displays mainly because it keeps the cost down and it is hard to reach a consensus of what should go on it so we leave this functionality entirely to the PDA or phone or desktop the reader is connected to.
You might think not having a display is a hindrance however when you are waving the device over tags quickly it is not convenient to try to watch a display on the reader at the same time. Having a small PDA in the other hand makes it easy. Larger integrated RFID devices have this problem and it can slow processes down because every time the user reads a tag they have to pull the device towards them to read the display. Our way shaves seconds off the whole process.
