How does it work?
A proximity card or prox card is a contactless smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and contact type smart cards. The proximity cards are part of the contactless cardtechnologies.
Prox cards use a low 125 kHz radio frequency to transmit to a door access reader. When the card is placed on the reader, the card's unique strand of numbers is passed to the access control panel, which verifies if the number matches an approved number in the internal database.
