单选题{{B}}D{{/B}} Will chips one day be planted in our bodies for identification? A US doctor has planted under his skin a computer chip that can send personal information to a scanner(扫描仪), a technology that may someday be widely used as a way to identify people. The chip gives off information which will be scanned by a hand-held reader. The chip is similar to those planted in more than one million dogs, eats and other pets in recent years to track and identify them. The doctor decided to test the chip himself after the Word Trade Center disaster. The dead could have been identified if their names and other important information had been chipped. Officials of the company said they hope to sell the chips to patients with man-made arms or legs or other body parts. The idea is that the chip will provide immediate and correct medical information when it is needed. The information can contain name, telephone number and other information. Or it can send out a message that, when connected to a computer, can call up records. The scanner can read it through clothes from over a meter away. The new product also could be used to control prisoners. Workplaces of great importance may want to use the chips for employees, too. Some parents may consider planting chips in young children or elderly relatives who may be unable to say their names, addresses or telephone numbers. Some medical and technology specialists said the product raises new questions about the relationship between humans and computer technology and could cause problems if it is used against someone's wishes, or if your personal information is read by those who should not see it.
