Proximity Card Systems
Proximity cards or simply "prox cards" communicate
through an antenna similar to contactless smart cards
except that they are read-only devices that generally
have a greater range of operation. The range of operation
for prox cards is typically from 2.5" to 20"
(63.5mm to 508mm) depending on the reader. It is possible
to read a small amount of information with prox cards
such as an identification code that is usually verified
by a remote computer; however, it is not possible to
write information back to the card.
Prox cards continue to grow in popularity because of
the convenience they offer in security, identification,
and access control applications, especially door access
where fast, hands-free operation is preferred.
