RFID(Remote Frequency Identification) is here. Approved for human use by the FDA in 2004, it's now a popular way for authorities (big brother government) to monitor its citizens.

Some religious beliefs relate this form of RFID usage to the 'mark of the beast' - as mentioned in the bible's book of revelations.

Likewise, many non-religious concerned citizens protest and detest the use of RFID on human beings.

However, marketing techniques overpower word of mouth, and therefore many people see this extent of governmental control as harmful and painless.

When a magician shoots your shoulder, turning it to stone, and shortly afterwards your friend throws a baseball at you, assuming you can catch it, but you cant because your shoulder is stone, so it hits it, and chips it. And in the ensuing rampage that you enter after having your shoulder inadvertently chipped, you accidentally kill your girlfriend.
