Among the companies that have been using RFID technology are Wal Mart, Tesco, Gilette, Microsoft, IBM and even the Department of Defense. Theses RFID tags aid these companies in finding or tracking any particular item or entity much easier. One can find these tags on clothes, food and even on weapons. Other than tracking, RFID can be used to create a controlled access to any structure or network. But whatever way the RFID is used, one thing is for sure - it enhances efficiency.

It is very similar to the barcode technology, but a lot faster. This is because unlike barcode which uses optical scanning, RFID uses radio waves to track a product. So, you don't have to place the tag exactly under the scanner. Just pass the Radio Frequency scanner and the tagged product is identified and tracked.
There are two types of RFID readers - Fixed RFID and Mobile RFID. As the names themselves suggest, the first one is stationary and the second one one can read RFID tags on the move.

Presently, a driving license has the entire driver's information on the back strip. This is inaccessible to anyone until the card is swiped. The new licences with RFID chips will ensure that the cards are not duplicated, but do place personal information at risk. Augustinowicz explains that anyone can steal the card's information in seconds if in range of RFID readers. He further adds that anything put into RFID chips should have physical protection because a hacker will always find ways of stealing the information.
Currently some states like Vermont, New York, Michigan, and Washington State have RFID chips in their drivers' licenses and offer security sleeves to protect them from being scanned, but these are not cent percent trouble-free.
