It is amazing how computer has almost taken over the whole earth. Almost everything can be done with the use of modern technology called computer and internet. You can shop without leaving home, make appointments, talk with loved ones who lives million miles away, and recording medical records. While at the hospital for 6 days treatments, I noticed that nurses and PCA, medical staffs and even an ordinary food servers use computer and barcode scanner. My bracelet was scanned many times. Could it be true that someday human will be scanned, too! How odd but if it would help track down criminals, then I would give my two thumbs up!
