What is an RFID Card and How Does It Work?

RFID (Radio Frequency Identification) cards are contactless cards that use radio frequency technology to transmit data. They are commonly used in access control, authentication, payment systems, and logistics.

Features of RFID Cards:

1. Contactless Communication: RFID cards can transfer data without requiring physical contact with the reader.
2. Secure Data Storage: The embedded chip securely stores identity and other information.
3. Fast and Efficient: Transactions are completed in milliseconds by simply bringing the card close to the reader.
4. Durable Design: Most RFID cards are resistant to water, impacts, and environmental factors.

Types of RFID Cards:

• Passive RFID Cards: Powered by the reader and are cost-effective.
• Active RFID Cards: Contain an internal battery and offer a wider range.
• Hybrid Cards: Combine multiple technologies in one card.

Applications:

• Access Control: Managing entry and exit in offices, hotels, or parking areas.
• Public Transportation: Enabling passengers to make quick and easy payments.
• Retail: Tracking inventory and streamlining checkout processes.
• Healthcare: Storing and accessing patient information.

RFID cards are a user-friendly and secure technology that has become an integral part of modern life. With applications that simplify processes in various industries, these cards will continue to find broader usage in the future.
