RFID is a general term used to describe systems that transmit product and service identities via radio waves. It is one of the latest and most effective identification technologies.

The main role of RFID technology is to validate the transmission of data from various devices, commonly called RFID tags, which are generally read by an RFID scanner and then prepared according to the needs of the application.

The RFID tags have a microchip connected to an antenna mounted on a substratum. Three kilobytes of data can be stored in every chip. The stored data can be retrieved by the reader, which has its own antenna that emits radio waves, which then receives a signal back from the tag. Information retrieved from the reader is transmitted to the host computer in digital form. 

Although expensive, they last longer and offer the best value with more storage capacity. There is no problem with positioning the RFID tag, the tag can be placed anywhere and doesn't even need to be visible to be scanned. RFID technology simplifies automated data collection processes and has many benefits for applications that use:

• RFID tags are stronger and safer and can work in harsh climates and harsh environments.

• They help reduce misplacement because they are easier to track.

• They increase product visibility, which makes it easier to use.

• RFID tags store information continuously and Quickly.

• RFID tags have a longer read range, making more sense in factories where they can be scanned with forklifts and remote scanners.
