Blurring the boundaries separating man from machine, a technology growing in popularity allows computer chips to be implanted under the skin.
This may be prohibited by the Bible but one rabbi warns of a greater danger: the chips could be used as a Nazi-like tool to control the populace.
The process is relatively simple. An identifying integrated circuit device or Radio-frequency identification (RFID) transponder encased in silicate glass approximately the size of a grain of rice is implanted under the skin using a device similar to a syringe. Local anaesthetic is used during the procedure. The use of subdermal RFID's for domestic and farm animals is widespread and some countries require them to be implanted This was first done by a physician in 1998 and was approved for use in humans by the Food and Drug Administration (FDA) in 2004.
