How it works!

An RFID system consists of two main components:

1. Transceiver: RFID Reader
2. Transponder: RFID Tag

The transceiver responsibility is to interrogate the transponder using its antenna. Hence, the RFID tag sends back its data to the reader and eventually to the backend server which the data is processed and responded accordingly.

While the tag is held within the reader’s coverage, the reader transmits radio frequency energy to stimulate the tag, which is oftenly called “Excite” or “Awakening” of the tag. The reader’s read range depends on number of factors such as the frequency used, polarization of both antennas used in the reader and tag, as well as the placement of the tag.

The transponder consists of two components itself:

1. IC: Microprocessor
2. Antenna

The RFID tag is a bundle consist of both microchip and antenna. tags are mainly designed to stick to the object which needs to be traced or read, therefore the size of tags has been shrinking over time as technology going forward upgrading.

After the reader excites the tag, signals sent by the reader is picked up by the tag’s antenna and responded oftenly with additional data which can be a track identification, serial number or even a customized information.
