Proximity cards, also known as prox-cards, are contactless integrated circuit devices used for security purposes, particularly in institutions to control access to restricted spaces and resources. These smart cards provide both physical and logical access control, allowing users to enter restricted areas and access computers and networks. Proximity cards are cost-effective and offer a good return on investment, and can also be used for additional functions such as email encryption, web authorization, and digital signatures.
Proximity card readers are easy to install and operate, using a simple mechanism to read and respond to digital signals from the access cards. Unlike swipe cards that require direct contact with a card reader, proximity cards can be presented from a short distance and still function effectively. Proximity card readers are also highly flexible and can be customized with features such as password and username keypads. Many proximity card readers use rechargeable batteries or have a battery backup system.
To protect their proximity cards and display them as access badges, employees should use proximity card holders. These holders should be provided with the cards and issued to new employees. By implementing a proximity card system, institutions can maintain control over access and ensure secure and efficient entry for their workers.
