RFID Technology – Some Primary Information

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’s based mostly on the same concept as barcode except that the tactic of encoding data is completely different since barcodes require a line of sight optical scan. As an computerized identification technology it reads encoded data with the aid of radio frequency waves. Its biggest advantage is that it doesn’t essentially need a tag or label to be seen 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 size of the tag is variable with some tags having memory space of up to 1 MB. Passive RFID tags don’t have an exterior power source 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-yr span. Passive RFID tags are programmed with a special set of data that can not 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 enclose it depending on the application it is going to be used for. The IC has an on-board memory that stores data. The IC uses the antenna to receive and transmit information to an exterior reader, usually referred to as an interrogator. Tags are also called inlays and transponders. In technical terms an inlay is simply a tag on a flexible substrate ready for conversion into a smart label. The smart label can extend the fundamental functioning of RFID by combining barcode technology and human readable information. Smart labels embrace 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 convenience of on-demand label printing.

RFID systems have variable frequency ranges, and the frequency level decides their use for zinedine01 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 dirt, and different environmentally tough conditions the place barcodes or any other optical identification systems would fail. Their high reading speeds are another advantage though RFID technology is more expensive.

At present almost every RFID implementation is different due to the performance requirements and value factors besides the signal transmission restrictions. They are used the place barcodes prove inadequate but that doesn’t males that RFID technology will change barcodes. The market is big enough for both to continue side by side.
