What Is RFID Card? Complete Beginner's Guide
Learn how RFID cards work, where they are used and why RFID technology is widely used for smart identity systems.
An RFID card is a smart plastic card containing a tiny microchip and antenna. RFID stands for Radio Frequency Identification .
These cards communicate wirelessly with an RFID reader and transfer information without physical contact.
RFID cards are widely used for employee attendance systems, access control, hotel key cards, student ID cards and smart security systems.
How Does an RFID Card Work?
Each RFID card usually contains:
- Microchip – stores information or unique identification data
- Antenna – sends and receives radio signals
- PVC Card Body – protects the chip and provides durability
When the card comes close to an RFID reader, the reader emits radio waves that power the card and retrieve stored data.
Types of RFID Cards
| Type | Frequency | Common Uses |
|---|---|---|
| Low Frequency (LF) | 125 kHz | Attendance systems and door access |
| High Frequency (HF) | 13.56 MHz | NFC cards, transport and libraries |
| Ultra High Frequency (UHF) | 860–960 MHz | Inventory and logistics systems |
