Card number is not read consistently

We bought a ZKTeco UHF6-18E-PRO and we encountered some issues with it. We configured it using the demo software and for a single physical card, we get 2 different card numbers. Is there a reason for this? Which of them is the real and actual one and how do we avoid this? Is there some other software or some way we can control it?


We changed the location of the device and now the tag is always read correctly. Could it be affected by interferences? Is it affected by metals, wires, anything like this?
