What is a Proximity Card?

Do you have a badge at work that lets you enter your building with a waive? If your answer is yes, then you have what is called a proximity card. A proximity card is a card that stores valuable and unique information (such as bank account info, employee identification and clearance level, etc.) that can be accessed conveniently and securely by a card reader. (There is a variety of other proximity technology available as well, such as proximity wristbands, proximity fobs, proximity rings, etc.)


How Do Proximity Cards Work? 

Proximity cards utilize a special type of technology called RFID (or Radio Frequency Identification) technology. RFID technology consists of a microprocessor chip that stores information and an antenna which allows that card to communicate with a card reader. Subsequently, the card reader uses the system preferences to determine whether or not the information on the card is valid and should be granted access. For example, if there are not enough funds in the user’s bank account, or if the employee does not have sufficient clearance, the system will deny the card access. Most commonly, proximity cards are used for security validation within a company by using card readers in tandem with electronic locks. 

Proximity cards come in different bit formats which help determine the type of information that can be stored on the card. (26, 34, 35, 37, and 50 are some bit formats.) The bit format you use directly correlates to the facility code of the card and ranges in many different identification numbers, making each card unique and secure. 


Why use a Proximity Card? 

Proximity cards can be used in a variety of ways by both private individuals and businesses. They are extremely user-friendly and provide a one-size-fits-all approach to security, making them more convenient than outdated methods of security like physical keys and passcodes. Whether you’re looking to secure your personal residence or an entire business, you should make the switch to proximity technology!
