RFID systems can be broken down by the frequency band within which they operate: low frequency, high frequency, and ultra-high frequency. There are also two broad categories of RFID systems-passive and active. In the sections below we will explore the frequencies and types of RFID systems. RFID Frequencies Frequency refers to the size of the radio waves used to communicate between RFID system components. RFID systems throughout the world operate inlow frequency (LF),high frequency (HF)andultra high frequency (UHF) bands. Radio waves behave differently at each of these frequencies with advantages and disadvantages associated with using each frequency band. If an RFID systems operates at a lower frequency, it has a shorter read range and slower data read rate, but increased capabilities for reading near or on metal or liquid surfaces. If a system operates at a higher frequency, it generally has faster data transfer rates and longer read ranges than lower frequency systems, but more sensitivity to radio wave interference caused by liquids and metals in the environment. The RFID frequency spectrum […]
Radio Frequency Identification (RFID) technology is making waves in the global festival, live event and brand experience markets. This secure electronic chip embedded into a wristband, card or lanyard is widely used in live events for Access Control, Cashless Payment, and Brand Amplification deployments. Events with integrated RFID solutions benefit from improved operational efficiencies, increased on-site revenue and an […]

Why are smart cards better than other ID token technologies? Smart cards are widely acknowledged as one of the most secure and reliable forms of an electronic identification (ID) token. A smart card includes an embedded integrated circuit chip that can be either a micro-controller chip with internal memory or a secured memory chip alone. […]
Buying a wallet used to be a relatively simple decision. You had your choice of a bifold, trifold, credit card sleeve or maybe just a money clip. Now if you flip through tech or gadget magazine, you’ll find a whole new genre of wallets that are designed with RFID blocking protection. Like this one from Common Fibers and […]
