RFIDs, as mentioned before, come in several different forms, each with its own advantages and disadvantages. Passive RFIDs do not have their own power supplies, but are limited to short range communications with the reader; Active RFIDs have longer ranges, but are more susceptible to interference.
Currently, in everyday use, we use RFIDs for theft prevention at stores. However, several companies have come up with several novel ideas to make lives easier.
Such a company is Metro Group
. Innovating from the warehouse to one's home, their concept of the RFID is prevalent throughout everyday life from when one reaches for the milk in the refrigerator to sorting clothes for the laundry machine.
Metro Group is one of several companies making the RFIDs that are placed in warehouses to account for inventory. They also have concept designs for refrigerators that tell the owner if he or she is out of milk; laundry machines that can detect when you've mixed in a red sock with your white laundry; mirrors that can take a snapshot of your physique so that you can try on the clothes that you picked out without actually having to wear them; and personal pads that you can carry around in a store, which document which items you are about to purchase. The last allows the shopper to pass through a scanner, with credit card in hand and, with the items already listed, payment is all but a swipe away.
All of these items mentioned, from the red sock to the milk to the new outfit, are all fitted with RFIDs, which originate from the warehouse with the original shipments. These RFIDs are integrated into our everyday lives so that you do not have to worry about minute things of everyday life.
