RFID Technology - Some Primary Details
RFID or Radio Frequency Identification, is the new technology talked about for product identification and data storage that can be utilized where barcodes fail. It is based on the identical concept as barcode besides that the method of encoding data is completely 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 doesn't necessarily want a tag or label to be visible to read the data stored.
RFID tags fall into two classes, active or passive. Active tags have an inside battery with a read and write option, permitting modification of data. The memory measurement of the tag is variable with some tags having memory house of up to 1 MB. Passive RFID tags do not have an external energy supply and instead use the facility generated from the reader. They're therefore lighter, cheaper, and have an unlimited lifetime of operation, unlike active tags have a ten-year 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 goes for use for. The IC has an on-board memory that stores data. The IC makes use of the antenna to receive and transmit information to an external reader, usually referred to as an interrogator. Tags are additionally called inlays and transponders. In technical terms an inlay is just a tag on a versatile substrate ready for conversion into a smart label. The smart label can prolong the basic 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 are often read via fog and snow, heat and mud, and other environmentally tough conditions the place barcodes or every other optical identification systems would fail. Their high reading speeds are another advantage even though RFID technology is more expensive.
At current nearly every RFID implementation is totally different as a result of performance requirements and cost factors besides the signal transmission restrictions. They're used where barcodes prove inadequate however that doesn't men that RFID technology will change barcodes. The market is big enough for each to continue side by side.
