However, the State Department soon received evidence that RFID readers could skim the information from the RFID tags from much farther than 4 inches - sometimes upward of 33 feet away. State Department announced it would issue electronic passports enabled with an RFID chip, it said the chips would only be able to be read from approximately 4 inches away. The frequency used will depend on the RFID application, with actual obtained distances sometimes varying from what is expected.

These run at 2.45 Ghzand can be read from 30-plus feet away. These range from 300 MHz to 960 MHz, with the typical frequency of 433 MHz and can generally be read from 25-plus feet away. The standard range is anywhere from a few inches to several feet.

High-frequency RFID system These range from 3 MHzto 30 MHz, with the typical HF frequency being 13.56 MHz.

LF RFID has short transmission ranges, generally anywhere from a few inches to less than six feet. These range from 30 KHzto 500 KHz, though the typical frequency is 125 KHz. Frequencies vary greatly by country and region. There are three main types of RFID systems: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF). RFID readers can be fixed (left) or mobile (right). Smart labels can be printed on-demand using desktop printers, where RFID tags require more advanced equipment. They can also be used by both RFID and barcode readers. These labels have an RFID tag embedded into an adhesive label and feature a barcode. Active RFID tags have a longer read range than passive RFID tags due to the stronger power source. The read range for RFID tags varies based on factors including type of tag, type of reader, RFID frequency, and interference in the surrounding environment or from other RFID tags and readers. Tags can be read-only or read-write, where data can be added by the reader or existing data overwritten. RFID tags typically hold less than 2,000 KB of data, including a unique identifier/serial number. Low-power, embedded non-volatile memory plays an important role in every RFID system. There are also semi-passive RFID tags, meaning a battery runs the circuitry while communication is powered by the RFID reader. A passive RFID tag receives its power from the reading antenna, whose electromagnetic wave induces a current in the RFID tag's antenna.

An active RFID tag has its own power source, often a battery. The part of an RFID tag that encodes identifying information is called the RFID inlay. RFID tags are made up of an integrated circuit (IC), an antenna and a substrate.

Tags that have a stronger power source also have a longer read range. The read range for RFID tags varies based on factors including the type of tag, type of reader, RFID frequency and interference in the surrounding environment or from other RFID tags and readers. The transponder is in the RFID tag itself. Once activated, the tag sends a wave back to the antenna, where it is translated into data. It uses radio waves to transmit signals that activate the tag.

The RFID reader is a network-connected device that can be portable or permanently attached. There are two types of RFID readers - fixed readers and mobile readers. When the scanning antenna and transceiver are combined, they are referred to as an RFID reader or interrogator. How does RFID work?Įvery RFID system consists of three components: a scanning antenna, a transceiver and a transponder. RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person. What is RFID (radio frequency identification)?
