RFID stands for Radio Frequency Identification.
Your objects are recorded using radio frequencies
There is no need to have visual contact with the RFID labels, as the range between the RFID reader and the RFID tag can be up to 4 meters.
the big advantage: you don't have to hold each label individually in the camera; all labels in a room are scanned in at once.
RFID tags have a strong hold and are highly resilient, you can use them for many years
Note: Non-metallic objects need different RFID tags than metallic ones. We can provide you with both.
