How RFID technology works

Author: Tzachi B

RFID technology uses radio waves to transmit information from a readers as well as an electronic tag mounted on an item for identification and monitoring reasons.

Tags (or inlays) have a memory nick as well as an antenna. Information within the memory nick can write, read increase many occasions throughout the existence from the product. Customers may also perform a number of actions with special RFID visitors, including securing the information within the nick, writing new data towards the nick, creating private areas, as well as "killing" the tag digitally after its final use.

Radio signals in the readers stimulate the tag. In reaction, the tag sends the initial identification quantity of the labeled object to the readers, along with other data saved around the nick. The writing process, or even the update from the tag data, is accomplished in the same way, by delivering a appropriate command in the readers.

Generally, the RFID tags could be classified into three primary groups:

Passive tags contain no internal power source, and normally don't transmit whatsoever. When there's a question in the readers an electromagnetic area sent in the readers and absorbed through the antenna from the tag the tag utilizes the absorbed energy to activate the nick and transmit the asked for information to the readers for decoding and processing data. Passive tags possess a reading through range as high as 8 meters.

Active tags come with an internal power source. Battery power built-into the tag allows the nick to deliver an indication to the readers even with no readers query. These tags can achieve a reading through selection of on the hundred meters.

Semi-active tags are occasionally known as semi-passive tags or Battery Aided Passive (BAP). Much like active tags, they contain an interior power source, but it's relatively small only big enough to supply energy to operate the nick alone. Like passive tags, broadcasting information to the readers requires energy absorbed in the reader's query but since the nick features its own internal supply of energy, semi-active tags can achieve a variety of hundreds of meters.

The communication process between your readers and also the tag is well-defined by a few worldwide methods and standards that are used by both tag and also the readers. Methods define the particulars and exact order of steps which are needed for communication between your tag and readers, including the phrase radiation frequency, transmission energy, transmission time, process ID from the tag, decoding procedure for the sent information and much more.

Frequency ranges generally employed for RFID systems are:

LF-Low Frequency range: 125-134KHz, reading through distance as much as 30 centimetres.

HF - High Frequency range: 13.56MHz, reading through distance as much as 1 meter.

UHF - Ultra High Frequency band: 868-928MHz range, reading through distance of countless meters.

RFID technologies have several benefits over uni-dimensional and bi-dimensional barcode technology, including:

Type of sight isn't needed between your readers and tag

Tag information could be added, up-to-date or transformed numerous occasions

Fast reading through time - read a large number of tags concurrently (versus. just one barcode at any given time)

Sturdiness tag can be put within the product or beneath a label, as opposed to a barcode label, which should be situated around the outdoors from the product and therefore uncovered to grime and damage that may disrupt the operation.
