RFID (Radio Frequency Identification) is a technology that uses radio waves to identify and track objects. In the context of cards, an RFID chip is embedded within the card, allowing it to be read and written to using a compatible RFID reader.
- Key components of an RFID card:
-
- Antenna: Receives and transmits radio waves.
-
- Microchip: Stores and processes data.
-
- Card Material: Typically PVC or PET.
- Types of RFID cards:
-
- Low Frequency (LF) RFID: Used for basic access control and proximity cards.
-
- High Frequency (HF) RFID: Used for contactless payments, access control, and data exchange.
-
- Ultra-High Frequency (UHF) RFID: Used for supply chain management, inventory tracking, and asset management.
- Benefits of RFID cards:
-
- Contactless convenience: No need for physical contact between the card and the reader.
-
- Durability: RFID cards are generally durable and can withstand wear and tear.
-
- Security: Can be equipped with security features like encryption and authentication.
-
- Versatility: It can be used in a wide range of applications.
- RFID cards are widely used in various industries, including:
-
- Access control: Granting or denying access card to buildings, rooms, or restricted areas.
-
- Payment systems: Contactless payments.
-
- Identification: Employee badges, student IDs, and government IDs.
-
- Supply chain management: Tracking products and assets.
