Proximity cards, also known as "prox cards" or "proxy cards," provide access and security without requiring insertion into a reader. They are a type of RFID card that contains an antenna and an ID chip embedded within the card. These cards interact with a proximity card reader to grant access or capture information.
This contactless approach makes these cards an excellent solution for many security and access applications, including parking lot access control, restricting access to secure areas and general building access. Because the cards do not need to be inserted or swiped, they are unaffected by snow, ice or rain, making them more reliable than magnetic stripe cards and perfect for outdoor use.
