摘要

Bar codes first appeared in 1972, and for the past 35 years these black-and-white coded strips have had little competition in the field of scanner identification. Bar codes basically consist of black ink patterns on paper that decode into information when read by a line-of-sight scanner. The question that many people now ask is: Will Radio Frequency Identification Tags (RFITs) soon replace bar codes? Many technology ex-perts expect RFITs to replace most bar codes by 2010. The illustration shows an electronic "Smart Label" made by Texas Instruments. Some airlines and shippers are already using "Smart Labels" to decrease processing time for luggage and other types of package deliveries. The smallest RFIT is smaller than President Jackson's eye on a 20-dollar bill, and it can track anything that it is attached to.
