Proximity card, also known as prox card or key card, is contactless smart card that use radio frequency identification (RFID) technology to transmit data to a reader. This card commonly used for access control, time and attendance systems, and other applications where secure and convenient identification is required.
How Proximity Cards Work:
- Radio Frequency Transmission: The card emits a radio signal when brought near a reader.
- Data Transfer: The reader receives the signal and decodes the information stored on the card.
- Authentication: The reader verifies the card’s authenticity and grants access or performs other actions based on the card’s data.
Key Features of Proximity Cards:
- Contactless Operation: No need for physical contact with the reader.
- Durability: Resistant to wear and tear.
- Security: Can be programmed with unique identification numbers to prevent unauthorized access.
- Flexibility: Can be customized with various features, such as magnetic stripes or smart chips.
Common Applications of Proximity Cards:
- Access Control: Controlling access to buildings, rooms, or specific areas.
- Time and Attendance: Tracking employee attendance and work hours.
- Event Management: Controlling access to events or venues.
- Asset Tracking: Monitoring the location of equipment or assets.
Advantages of Proximity Cards:
- Convenience: Easy to use and carry.
- Security: Reduces the risk of lost or stolen cards.
- Durability: Resistant to wear and tear.
- Flexibility: Can be customized to meet specific needs.
- What is a proximity card
A proximity card, commonly referred to as a prox card, key card, or keycard, is a type of contactless smart card that can be read without the need for physical insertion into a reader device. This contrasts with older magnetic stripe cards, such as credit cards, and contact-type smart cards, which require direct contact. Proximity cards are integral to the advancements in contactless card technologies.
