What are "proximity access cards"?

• A. Cards that require a physical key for entry
• B. Cards that use RFID technology and can be read from a short distance without physical contact
• C. Cards that can only be used at specific locations
• D. Cards that store personal identification information

Answer: (B)

Proximity access cards utilize RFID (Radio Frequency Identification) technology, enabling them to be read from a short distance without the need for direct contact with the reader. This means that when a user is within a few inches of the designated reader, the card transmits its information wirelessly, allowing for quick and seamless access. This feature enhances convenience and efficiency, particularly in access control systems where users may need to gain entry quickly, such as in secure buildings or restricted areas. The method of operation distinguishes these cards from conventional systems which may require insertion, swiping, or other forms of physical interaction. This technology also allows for multiple cards to be read in quick succession, which is particularly useful in high-traffic areas. Thus, the defining characteristic of proximity access cards is their ability to function without physical contact, which streamlines the process of entry and enhances user experience.
