RFID Cross Reading Problem — most systems don’t fail where people think
There was one warehouse project I still remember clearly, not because it was complex, but because it was slightly annoying to debug. Everything looked normal. Two gates installed. UHF system running. Rfid Tags responding fine. But the inventory records were… messy. A pallet moving through Gate A would sometimes appear in Gate B’s logs. Even worse, sometimes tags from a nearby staging area were getting picked up during peak traffic. Nobody noticed it at first. Then someone compared timestamps and things stopped making sense. At that point, people usually start blaming the RFID system. Or the rfid antennas . Or the rfid reader. But it didn’t feel like a “broken device” situation. More like a control problem. The “cross reading” issue usually doesn’t look like a failure at first RFID cross reading problems are a bit deceptive. It doesn’t crash. It doesn’t stop working. It just slowly becomes unreliable. You see things like: tags showing up in the wrong zone duplicate reads across d...
