Limitations of RFID

LIMITATIONS OF RFID

                                                

·         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 is a limit as to how deep the RF energy can reach, even through RF-lucent objects.

·         Immature technology. Although it is good news that the RFID technology is undergoing rapid changes, those changes can spell inconvenience for the unwary.
