A HID proximity card reader is a device used to read data stored on proximity cards, which are a type of contactless smart card used for access control and security. Here’s an overview of its key features and functions:
How It Works:
- Radio Frequency Identification (RFID): HID proximity cards use RFID technology to communicate with the reader. The reader emits an electromagnetic field that powers the card when it is within range.
- Card Communication: When a card enters the reader’s range, it transmits its unique identification number back to the reader.
- Data Transmission: The reader sends this information to a control panel or computer system, which then determines if the cardholder has authorization to access the area.
Key Features:
- Contactless Operation: Users simply need to present their card near the reader (typically within a few inches) for the system to read the card’s data.
- Security: Proximity cards are difficult to duplicate, providing a higher level of security compared to traditional keys or swipe cards.
- Convenience: Quick and easy access without the need to physically swipe or insert a card.
- Durability: Since there is no physical contact with the reader, proximity cards and readers are generally more durable and require less maintenance.
Applications:
- Building Access Control: Commonly used in office buildings, schools, hospitals, and other facilities to control entry to restricted areas.
- Time and Attendance: Integrated into systems for tracking employee attendance.
- Parking Systems: Used for granting access to parking facilities.
- Secure Printing: Ensures that documents are printed only when the authorized user is present.
- Examples of HID Proximity Card Readers:
– HID ProxPoint Plus: A compact and versatile reader for indoor and outdoor use.
– HID ProxPro II: Offers a longer read range and higher durability for more demanding environments.
– HID iCLASS SE: Provides additional security features such as encryption and mutual authentication between card and reader.
HID (Hughes Identification Devices) is a leading manufacturer of such proximity card readers and provides a variety of models to suit different security needs and environments.
