Abstract

This article examines the growing use of contactless or proximity transit cards and technology, otherwise known as cards. Smart cards send a radio signal to a target at the fare gates which open and automatically debit the proper amount from the prepaid card. About 66,000 smart cards are in circulation in Washington, DC's transit system, which carries some 300,000 passengers/day. It is the largest transit system in the country operating with smart-card technology and is viewed as a national model. Many other major metropolitan areas are in the midst of procuring or are considering similar systems including Chicago, Seattle, and San Francisco. The implementation of these systems and the many advantages of smart card technology are discussed.
