RFID Smart Card (Pack of 5) 

The RFID Smart Card (Pack of 5) is a high-quality contactless identification card designed for secure access control, attendance management, authentication, and data identification applications. Each card contains an embedded RFID (Radio Frequency Identification) chip and antenna that communicate wirelessly with compatible RFID readers, enabling fast and reliable data exchange without physical contact.

This pack includes 5 RFID smart cards, making it suitable for offices, educational institutions, hotels, residential complexes, industrial facilities, membership programs, libraries, parking management, and various automation systems. The cards provide a convenient and efficient method of identifying users while improving security and reducing manual record-keeping.

Each RFID card is manufactured from high-quality PVC material, offering excellent durability, flexibility, and resistance to moisture, dust, scratches, and daily wear. The smooth surface can also be printed or labeled with identification details, making it suitable for personalized ID cards and access badges.

The cards operate using Radio Frequency Identification (RFID) technology, typically at 125 kHz (LF) or 13.56 MHz (HF) depending on the model. When an RFID card is brought near a compatible reader, the electromagnetic field generated by the reader powers the passive RFID chip inside the card. The chip then transmits its unique identification number or stored information back to the reader without requiring a battery or physical contact.

The contactless operation provides quick authentication, improves convenience, and reduces wear compared to traditional magnetic stripe or contact-based cards. The RFID cards can be easily integrated into Arduino, ESP32, Raspberry Pi, STM32, and other microcontroller-based RFID systems using compatible RFID reader modules such as the RC522 or RDM6300.

Whether you are developing an IoT project, implementing an attendance system, creating an access control solution, or replacing existing RFID cards, this RFID Smart Card Pack of 5 delivers dependable performance, secure identification, and long-lasting durability.

Working Principle

The RFID Smart Card operates using radio frequency communication:

• The RFID reader generates an electromagnetic field.

• The passive RFID chip inside the card receives energy from the reader.

• The chip becomes active without using an internal battery.

• The card transmits its unique identification number or stored data back to the reader.

• The reader verifies the information and grants access or records the data according to the system configuration.
