It is undeniable that RFID tags reign over the bar coding technologies and other optically read technologies due to its contactless nature, larger memory capacity and ability to allow energy to penetrate certain goods that are hidden or covered with substances such as snow, fog, ice, dirt, paint or crusted grime. In this article, the frequencies used in different RFID systems are compared. The frequencies can be divided into low frequency (LF), high frequency (HF), ultra high frequency (UHF) and microwave. The two most popular frequencies used in today's applications are HF and UHF. HF refers to the frequency 13.56 MHz, while UHF refers to the frequency range from 860 to 956 MHz in the radio spectrum. Which is the better one?
