Problems of RFID tags

  1. No standard universal protocol defined yet, for the responding frequencies of RFID tags. (Frequencies in USA are currently incompatible with those in Europe or Japan).
  2. Security Problems – The tags which are world readable may pose a risk to privacy, military security etc.
  3. Since RFID systems make use of the electromagnetic spectrum they are relatively easy to jam using energy at the right frequency.
  4. Collisions may occur between readers and/or between tags.
  5. Implanted tag, to a person, can be read without his permission.
