Internet of things consists of all Internet-enabled products and web services. It is a term related to the growing interdependence of the world. Internet of things is already a reality in some environments, but its use is expected to increase rapidly in the near future.
Internet of things makes use of a number of technologies, including RFID tags and QR codes that can be attached to the item, and sensors and devices that can be used to read the information encoded in the tag.

The internet of things requires the use of sensors and devices that can read these tags and use the information they hold. These sensors may be able to read the information in the distance, but they could also demand greater proximity of the tag to read. For example, RFID tags on laboratory samples can be read by sensors placed at each door.
The information detected by the sensor can be made available on the Internet, not only on devices that read the labels. The elements can be detected by sensors at various stages or locations in the delivery process and the current location of the item can be made available to customers on the company's website.
