RFID stands for Radio Frequency-Identification, and it describes the encoding of digital tags in RFID tags. It also refers to a variety of tracking systems that utilize smart barcodes to identify various items.

RFID tags function by the transmission and collection of information through a microchip and an antenna. The microchip embedded on an RFID reader contains the information the handler wants.

Generally, there are two major types of RFID tags: Passive RFID tags and Battery-operated RFID tags.

For the Passive RFID tags, three major frequencies are used to transmit information, and they are:

• Low Frequency- 125-134 kHz
• High Frequency and Near-Field Communication- 13.56MHz
• Ultra-High Frequency- 865-960 MHz

When a reader scans a passive RFID tag, it sends energy to the tag and powers it sufficiently to allow the antenna and chip to transmit information to the reader. Then, the reader sends the information to an RFID computer program for interpretation.

While the Battery-operated RFID tags, they contain a built-in battery for power supply. And this is one of the distinctive features between battery-operated RFID tags and passive RFID tags.

There is a high demand for RFID technology in various fields, and the list below shows some of the tasks that the RFID technology performs.

• Management of Inventory
• Badging of IDs
• Tracking of Assets
• Prevention of Counterfeit products in the Pharmaceutical line
