摘要
Various problems posed by radio frequency Identification systems and their solutions are presented. RFID could help stamp out drug counterfeiting, trace contaminated beef products to eliminate supermarket checkout lines. RFID tags can be read at a distance without a person's knowledge. As a result, tags placed in consumer items for one purpose might be convertly used to track people as they move through the world. Most RFID systems operate in the radio spectrum's unlicensed portion, where regulations govern power output for readers. This characteristic, combined with physical limitations, limits the reading range for passive tags, which are powered by the radio signal that reads them.
