In the very near future you will no longer have to worry about forgetting your computer password, your cash card number or even your keys, because your body will be your ID. Finger scanning, which is similar to fingerprinting, is already being used by large companies to identify employees. Face recognition is another growing area of ID technology, as are voice and eye recognition. Something quiet new on the market is footstep identification. Using special floor tiles, computers are able to identify people from the way they walk. This technology will let your employer or your teacher know exactly where you are and what you are doing while you are at work or at school.
