There are no such government laws regarding RFID. RFID technology works on AIDC (Automatic Identification and Data Collection) and uses radio frequencies to transfer information. The radio waves, if they transmit a high level of frequencies, can harm human beings and animals. There is no global body present that controls the RFID frequencies. Globally, EPCglobal Gen-2 and ISO 18000-6C standards are adopted in every country. According to the standards, the optimum frequency bandwidth that can be used is 860- 960 MHz. These are kind of guidelines because no law has been framed on these guidelines. Different countries have set different standards in line with global standards. Department of telecommunication that comes under the ministry of communications and information technology, issues the guidelines in India regarding RFID frequencies. It has delicensed the spectrum in the range of 865-867 MHz for RFID applications. In this frequency band, only 4 W ERP, 1 W transmitter power and 200 kHz carrier bandwidth is allowed. In other words, the frequency range more than 865-867 MHz band can not be crossed in any application.
The Federal Communications Commission (FCC), an independent agency that controls communications in the US, have set a standard related to various frequency bands in FCC part 15 rules. It has determined a 902-928 MHz frequency band for supply chain activities. Moreover, it has set rules and regulations regarding the 865-867 MHz frequency band too. Japan has set the standard of using a 952-954 MHz frequency band with a maximum of 4 W ERP. It has also kept a licencing system for using the high powered systems.
