RFID Technology – Some Primary Facts

RFID or Radio Frequency Identification, is the new technology talked about for product identification and data storage that can be used where barcodes fail. It is based on the same idea as barcode except that the strategy of encoding data is totally different since barcodes require a line of sight optical scan. As an automated identification technology it reads encoded data with the aid of radio frequency waves. Its biggest advantage is that it does not essentially want a tag or label to be seen to read the data stored.

RFID tags fall into two categories, active or zinedine01 passive. Active tags have an inner battery with a read and write option, allowing modification of data. The memory dimension of the tag is variable with some tags having memory area of up to 1 MB. Passive RFID tags would not have an external power source and instead use the ability generated from the reader. They are therefore lighter, cheaper, and have an unlimited lifetime of operation, unlike active tags have a ten-12 months span. Passive RFID tags are programmed with a particular 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 connected to an antenna and a protective packaging is used to surround it depending 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, typically referred to as an interrogator. Tags are additionally called inlays and transponders. In technical terms an inlay is solely a tag on a versatile substrate ready for conversion right 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 are often read by fog and snow, heat and dust, and other environmentally robust conditions the place barcodes or any other optical identification systems would fail. Their high reading speeds are one other advantage despite the fact that RFID technology is more expensive.

At present virtually every RFID implementation is completely different due to the performance necessities and cost factors besides the signal transmission restrictions. They’re used the place barcodes prove inadequate however that does not males that RFID technology will exchange barcodes. The market is big enough for both to continue side by side.
