How does RFID Work?

RFID stands for Radio Frequency Identification a system that transmits the identity of an object or person wirelessly using radio waves. RFID technology allows you to update the information read by readers, unlike barcodes. It also makes it quicker to scan items, as RFID is considered an automatic identification technology. Each RFID tag contains a microchip where the data is stored and antennae to read the information associated with each tag. The data encoded in RFID tags, about the item that has been tagged, is captured by RFID readers through radio waves.

The popularity of RFID has grown tremendously in the past decade as it can track items within a supply chain making it easier to manage. Companies such as Walmart, who have adopted this technology have contributed to its wide spread use. RFID is not limited to use in retail stores. In fact it can be used to track anything.
