RFID, radio frequency identification is an advanced technology that makes use of the radio waves as the signals for data exchange between the electronic tag and reading machine, is attached in remote locations. This latest technology is presently used for tracking and identification. This is a completely new technology that is utilized for logistics, inventory, in hospitals and libraries.
The basic technology of this latest device includes the tags and reading equipment. The data is communicated between them with the help of radio waves. Generally, in RFID one can get to see around three kinds of tags - Active tags, passive tags and passive tags which are assisted with batteries.
The former tags are completely operated on battery, the passive tags do not have any source of power and the passive tags which are assisted by batteries require some external sources for functioning. RFID tags also include circuits that read signals as well as store data. Antennas are also included for sending and receiving signals.
Consumer advocates are concerned mostly about the RFID potential to invade the privacy of individuals. The RFID technology proponents have minimized the unsubstantiated fears by putting huge emphasis on the factors like how this technology does not have or will never have the ability which is required for the privacy invasion envisioned. The myths related to this technology that need to be debunked are mentioned below:
Tags can be encrypted or otherwise secured
The crucial tag data will never serve as an open book for anyone having a reader. Tags are certainly not foolproof, but as it is with e-commerce, the improved encryption will ensure complete security for the usage. And when it comes to the internet, it solely depends on the customers whether they wish to accept the additional risk.
Readers will not be ubiquitous
Projects that are RFID implemented are just not developed centralizing the idea of implanting readers, so that individually tagged items can be scanned on a continuous basis.
Limited scanning range
Certain scenarios that depict FBI or criminal agents parked outside the homes and using RFID readers who do not take the EPC global tags into account are usually passive and they operate at the UHF frequency, which does not interact with water and metal properly. Tags that are placed next to the human bodies are unreadable.
