HID Proximity Card Reader is designed to read HID proximity cards, which are a type of contactless card operating at a low frequency of 125 kHz.
How HID Proximity Card Reader Work:
- HID proximity card readers use radio-frequency identification (RFID) technology to communicate with HID proximity cards.
- When a card is brought within the reader’s range (typically a few inches), the reader emits radio waves that power the card’s internal circuitry.
- The card then transmits its unique identification number (UID) to the reader.
- The reader then sends this ID to an access control system, which determines whether to grant access.
Key Features of HID Proximity Card Readers:
- 125 kHz Operation: They operate at a low frequency of 125 kHz, which is the standard for proximity cards.
- Read-Only Functionality: Most HID proximity card readers are read-only, meaning they only read the unique ID from the card and don’t write any data to it.
- Various Form Factors: HID offers a wide range of reader form factors, including wall-mounted readers, mullion-mounted readers, and desktop readers, to suit different installation needs.
- Wiegand Output: Many HID proximity card readers use a Wiegand interface to communicate with access control panels.
- Durable and Reliable: HID readers are known for their durability and reliability, designed for long-term use in various environments.
- Secure Options: While proximity technology is inherently less secure than smart card technology, HID offers some readers with enhanced security features like encrypted communication.
Common Applications:
HID proximity card readers used for:
- Access Control: Securing entry to buildings, offices, and restricted areas.
- Time and Attendance Systems: Tracking employee clock-in and clock-out times.
- Parking Management: Controlling access to parking facilities.
- Other Identification Applications: Where a basic level of authentication is required.
