　　Identifying Chips

　　No bigger than a grain of rice and embedded beneath a person’s skin, the computer identifying chips will be the future ID card someday.

　　ID cards are easy to counterfeit while the chips are extremely hard to remove or fake. In addition, the chip has no power supply; rather, it has a millimeter-long magnetic coil that is activated when a scanning device is running across the skin above it. A tiny transmitter on the chip nds out the data. But without the scanning device the chip can’t be read. By limiting the u of scanners can people control what the technology is ud for. airports, nuclear plants and other high-curity facilities to avoid the problem of negligence on the part of curity guards. Other us include satellite tracking of an individual’s energy movement to the storage data such as medical records. So it’s good news for tho who are afraid of being kidnapped, requiring paramedical rvices or suffering from rious allergies. Besides, with chips which can be implanted into animals being made, owners can find the lost pets with ea.

　　Have you lost your ID card? No, it’s still in your body.
