3.1. Limitations of RFID
The current limitations of RFID include the following:
Poor performance with RF-opaque and RF-absorbent objects. This is a frequency-dependent behavior. The current technology does not work well with these materials and, in some cases, fail completely.
Impacted by environmental factors. Surrounding conditions can greatly impact RFID solutions.
Limitation on actual tag reads. A practical limit applies as to how many tags can be read within a particular time.
Impacted by hardware interference. An RFID solution can be negatively impacted if the hardware setup (for example, antenna placement and orientation) is not done properly.
Limited penetrating power of the RF energy. Although RFID does not need line of sight, there ...
