RFID Technology - Some Fundamental Information

 

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's based on the identical idea as barcode besides that the tactic 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 need a tag or label to be visible to read the data stored.

 

 

RFID tags fall into classes, active or passive. Active tags have an inner battery with a read and write option, permitting modification of data. The memory size of the tag is variable with some tags having memory area of up to 1 MB. Passive RFID tags don't have an external energy supply and instead use the facility generated from the reader. They are due to this fact 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't 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 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 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 flexible substrate ready for conversion right into a smart label. The smart label can extend the basic 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 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 means of fog and snow, heat and dirt, and different environmentally powerful conditions where barcodes or some other optical identification systems would fail. Their high reading speeds are one other advantage even though RFID technology is more expensive.

 

 

At current nearly every RFID implementation is completely different due to the 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 sufficient for both to proceed side by side.
