Radio frequency identification (RFID) technology uses radio waves to automatically determine identity. For example, an RFID chip can associate a particular serial number with a particular person or object. Then, it transmits information about the movement of the person or object to which it is attached by electromagnetic waves. RFID was first used in the 1970s, and RFID has become more common as production costs have fallen.

At present, many clothing companies are already using RFID technology. They attach RFID tags to the clothing, track the number of times the consumer has tried on a piece of clothing in the mall to get the consumption data and the inventory quantity of the clothing. There are also companies that attach RFID tag to the socks so that customers can track their exact location, whether the other socks are hidden in the dresser drawer or under the bed, even if the two socks are mismatched, they can find out.

Socks with radio frequency identification (RFID) chips have a radio-emitting tag that sends the signal via Bluetooth to the APP on the smartphone. Users can find the exact location of the socks by using this APP. It also lets them know the key information, such as whether the socks have been washed, how long they have been washed, and so on.

Two schools in San Antonio, Texas, used similar technology. Using RFID technology to track students’ actions on campus, you can grasp the precise number of people to protect students’ safety, and also let the school better manage student behavior, such as knowing students who skip classes.
