Disadvantages of RFID RFID technology

source:Anhui Etown Information Technology Co.,Ltd   Update time:2021-09-26

1、RFID costs are too high, plus RFID transmitters, readers, encoders and antennas and other equipment costs are high.


2、Privacy issues are involved. Possible leakage of national security information/secrets.


3、Once the RFID tag is close to the reader, it automatically sends an unconditional message. It cannot confirm whether the RFID reader is legitimate. For example, in People's Daily life articles, the owner of such articles (such as clothes) may not be aware that the articles have been embedded with electronic tags in advance and may be scanned, positioned and tracked without control, which is bound to infringe personal privacy. The key to the privacy issue is the basic function of rfid tags: the ID or identification number of any tag can be arbitrarily scanned remotely, and the tag automatically and indiscriminately responds to the reader's commands and transmits its stored information to the reader.


4、Objects or environments that contain metals and moisture can affect RFID.


5、Different countries open frequency band, there are still consistency problems.
