What are the disadvantage of RFID in information security?

In RFID, it is a technology that incorporates the need of electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum to uniquely recognize an object, animal or person.

The slow cost adoption of the RFID technology in the mass industry even after the presence of a large number of advantages clearly points that this technology is not ready for such a broad spread adoption because of a number of limiting factors. There are various disadvantage of RFID which are as follows −

  • The RFID technology proves to be unreliable in channels such as metals or liquids where RFID tags fails to be read.

  • RFID technology, in spite of its bigger reliability than electromagnetic strips and bar codes, is to be perfected as an important percentage of the RFID tag fails to function properly.

  • RFID tags can suffer from orientation issues as sometimes these tags do not connect with the readers when both are misaligned concerning each other.

  • The non-adoption of line of sight technology of the bar code leads to a major security disadvantage in parallel to its ease of use. The need of high gain antenna by a competitor can lead to loss of confidential data of products connected with RFID tags as the information included within these tags can be simply picked up by such antennas.

  • RFID technology comes with some major financial disadvantage as for the need of RFID tags, a specific adopter has to first install RFID reader(s) and computer networks for assessing the data in the RFID tags. This leads to a low-cost installation cost and as such a technology confirm to be futile from an economic view.

  • RFID technology has a signal threshold like in the cellular connection field which RFID technology becomes non-functioning. Moreover such a technology can malfunction in areas with large signal interference.

  • After reading a high number of RFID tags, it can appear in rare cases that the reader sometimes administers tag which does not exist therefore leading to an error in the database entry. Such a problem is called a Ghost Tag problem in RFID.

  • The facilitation of automated environment in the work place by the acceptance of RFID tags in the several sectors of an industry such as library management of assets, verification at checkouts etc. leads to reducing demand of human workforce which leads to widespread unemployment in a region.

  • RFID tags are affected to elimination from an object with ease.

  • Interference between tags located within .125th of an inch from each other can take place.
