Does the use of metal trolleys and metal lined trucks effect the RFID system?
In a similar way that tin cans short out the operation of transponders on the metal surface, similar issues arrise when the container is metal. However in the situation of metal trucks and containers, the presence of metal can be an advantage as it contains the RF energy, but interaction between the direct waves and those that bounce off the walls do cause zones of varyiing energy density in different locations in the reading area. Trolleyponder have addressed this problem and with correct reader and system design, can wipe out these zones to get uniform operation in most areas within the container.
