Proximity CardsProximity CardsProximity cards contain an antenna and an IC chip containing storedinformation. Usually the cards contain the same type of cardholderinformation as Wiegand cards. Readers and cards are available in a number offrequencies and technologies. Some readers are able to read several differenttypes of cards, while others are limited to a single format.The most common proximity cards are “passive”; the radio frequency fieldgenerated by the card reader energizes the card and allows the IC chip totransmit its data. Most readers require the card to be placed within a fewinches of the read head. A few types of “long range” readers have effectiveranges out to several feet.The obvious advantage of the proximity card is that it may remain in a pocketor handbag, hang from a belt, or even be attached to a vehicle and still beeffective.Most modern proximity readers use a Wiegand-style output, with Wiegand36 and 37 being the most popular.
