RFID Technology - Some Fundamental Info
RFID or Radio Frequency Identification, is the new technology talked about for product identification and data storage that can be used the place barcodes fail. It's primarily based on the same concept as barcode besides that the tactic of encoding data is different since barcodes require a line of sight optical scan. As an automatic identification technology it reads encoded data with the aid of radio frequency waves. Its biggest advantage is that it does not necessarily want a tag or label to be seen to read the data stored.
RFID tags fall into categories, active or passive. Active tags have an internal battery with a read and write option, permitting modification of data. The memory dimension of the tag is variable with some tags having memory house of up to 1 MB. Passive RFID tags shouldn't have an external power supply and instead use the ability generated from the reader. They're subsequently lighter, cheaper, and have an unlimited lifetime of operation, unlike active tags have a ten-yr span. Passive RFID tags are programmed with a special set of data that cannot be modified and being read-only, they operate as a license plate in a database.
Passive RFID tags have a low-power integrated circuit hooked up to an antenna and a protective packaging is used to surround it relying on the application it is going for use for. The IC has an on-board memory that stores data. The IC makes use of the antenna to obtain and transmit information to an exterior reader, usually referred to as an interrogator. Tags are additionally called inlays and transponders. In technical phrases an inlay is simply a tag on a versatile substrate ready for conversion into a smart label. The smart label can lengthen the fundamental functioning of RFID by combining barcode technology and human readable information. Smart labels embody an adhesive label embedded with an RFID tag inlay. Thus they provide the benefits of read range and the unsupervised capability of tags, with the flexibility and comfort of on-demand label printing.
RFID systems have variable frequency ranges, and the frequency level decides their use for applications. Their biggest asset is their operation without a line-of-sight and without contact. Thus they can be read through fog and snow, heat and mud, and other environmentally robust conditions where barcodes or some other optical identification systems would fail. Their high reading speeds are another advantage though RFID technology is more expensive.
At current almost each RFID implementation is different because of the performance necessities and value factors besides the signal transmission restrictions. They are used the place barcodes prove inadequate but that does not males that RFID technology will replace barcodes. The market is big enough for both to proceed side by side.
