So now we know what RFID is. Let's discuss some examples of RFID. So as mentioned before ,RFID is great for tracking and tracing inventory, applying to the physical retail stores, RFID can be used for loss prevention purposes to alert stolen items. When you check out the item. This system essentially the activates the RFID allowing the shopper to pass through the intimidating RFID exit ,timing marathons and races or some of the most popular use cases of RFID . To non runners like me, this was news to me. But companies like race wire in bed RFID tags onto the number bibs to track race time of participants. Pretty cool. Last but certainly not least, this goes out to all pet owners out there. You can have a micro implant a RFID chip to track and identify your pet. The chip is about the size of a rice grain and not harmful to pets.
