This is nice subject that I just want to share with you guys.. I think it's not hard to really understand how this thing works....
RFID or Radio-frequency identification according to wikipedia is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders...
If you're familiar with those yuppies working in Makati where they swipe a card(about the same size of your ATM card) to login and logout in there offices then it's easy to go about this technology... This card has a built in chip that stores data of the one who owns it..Once this guy swipes his card the record goes to the database and storing the time and code of that card..
Though this is pricey compared to using bar codes (supermarkets), RFID will soon replace this because of the advantage it will do concerning security of the items while being transported...

But some are skeptical about this technology because the government might use it on their advantage by literally inserting the chip under the skin of their subject to track their location.. As reported before, somewhere in Mexico they did this to their employees to regulate the access to a highly secure data room...
