The Main Elements of RFID Delhi

RFID or Radio Frequency Identification involves the wireless use of electromagnetic fields for transferring data for the purpose of tracking and identifying tags that are attached to different objects automatically. These tags contain information that is stored electronically. RFID systems feature tags and readers that communicate with each other by way of radio waves. There are a number of elements that comprise the entire system of RFID Delhi. The elements are as follows:

RFID Readers or Writers

RFID readers in India are used for communicating with RFID tags. These are devices that are used for interrogating RFID tags. The readers feature an antenna that carry out the task of emitting radio waves. The tags respond to these waves by transferring back data. Here, the writer is used for writing data on the tags.

RFID Tags

Coming to RFID tags, they are microchips combined with antennas in compact packages. The packaging is duly structured in a way to allow the tags to be easily attached to objects that need to be tracked. There are basically two varieties of RFID tags and they are active and passive tags. Active tags come with batteries that can effectively be used in the form of complete or partial sources of power for the antenna and the circuitry of the tags. There are even some tags in this category that feature replaceable batteries offering years of uninterrupted usage.

The passive RFID tags do not come with batteries and they get power from readers. When radio waves from the readers encounter the passive tags, the coiled antenna of the tag forms an electromagnetic field. This is where the tag gets power from and thus its circuits get fully energized. The tag then carries out the task of sending information that is encodes in its memory. Dealers in India are also into handling RFID tags exports mainly because RFID tags manufactured in India are known for their durability and their quality.
