A proximity card or prox card [1] also known as a key card or keycard 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. [2]
A prox card (short for proximity card) is a contactless smart card used to control physical access to secured areas. These cards use RFID (Radio Frequency Identification) technology to communicate with readers without needing to be physically inserted, swiped, or tapped.
Proximity Cards (Prox cards for short) are a form of contactless smart card that is able to be identified and read without the need to be inserted into a reader. They have become a popular and emerging technology in recent years and are often used in access control for ID cards.
Proximity card readers are an integral part of an access control system. These are touchless devices that read the credentials of a token or proximity card when it’s within the detection radius. So, what is a proximity card, and how does it differ from other access cards?
A proximity card is a cost-effective and reliable solution to control who has access to your building premises. It works on the principle of radio frequency, first proposed by Heinrich Hertz in the late 1880s. The microchip (coil in outdated cards) embedded on the prox card stores a number pattern.
What is a Proximity Card? A proximity card, also often called a prox card, is a technology card that can be read without being inserted into a card reader. Proximity cards contain an embedded antenna coil which contains all of the encoded card data.
Proximity cards are contactless ID cards or key fobs that you wave in front of a door reader to gain access to a building. These technology cards use RFID (radio frequency ID) which is a wireless technology that enables communication with the access control server, deciding whether to allow entry to the user.
Proximity cards, also known as HID proximity cards, are the ideal addition to workplace security systems where human interaction isn’t always possible. It allows authorized employees to enter the building and limits unauthorized individuals from accessing areas with sensitive data.
Proximity cards, also known as Prox cards or access control cards, are contactless ID cards or keyfobs containing programmed data. The data, or code, is “read” by a card reader and transmitted to an access control panel to control and secure physical access.
Proximity cards are contactless cards that do not require to be inserted inside a device for it to be able to read information. A proximity card can be read by a device even while it is kept inside a purse or wallet.
