As much as i don't like this chip, there are some downsides and good sides.
Downsides are that it registers criminal records and shows if you're legit to enter some high-tech facilities where there's high level security. Otherwise it won't be needed, unless for keeping criminal records or travelling.
Good sides:
1. When ever you will experience that somebody has stolen your ID, you can always prove that you're you.
2. Chips will make doctor's works alot easier when there are some major injuries so that the victim is not able to tell his/her name/ID.
3. The goverment certainly is NOT watching EVERY move you make. They would need like 93 million eye pairs to get something that utopic done to watch over everyone. The chip is NOT a god damn GPS system that it will track you down 24/7 on the entire world.
4. If you ever want to start a fresh page, just be emo and cut the chip out of your body part.
