RFID Smart Card (10 Pcs)

The RFID Smart Card (10 Pcs) is a set of contactless Radio Frequency Identification (RFID) cards designed for wireless identification, authentication, and access control applications. These cards contain an embedded RFID integrated circuit (IC) and an internal antenna that enable communication with compatible RFID readers without physical contact. RFID smart cards are widely used in access control systems, attendance management, security systems, payment systems, public transportation, library management, inventory tracking, educational projects, IoT devices, and embedded system applications.

Each RFID smart card is manufactured from high-quality PVC (Polyvinyl Chloride), making it lightweight, durable, waterproof, and resistant to everyday wear and tear. Inside the card is a 13.56 MHz RFID chip (commonly MIFARE Classic 1K or a compatible chip, depending on the model) connected to a thin copper antenna embedded within the card body. The antenna receives power from the electromagnetic field generated by an RFID reader, eliminating the need for an internal battery.

The working principle of the RFID Smart Card is based on radio frequency communication. When the card is brought within the operating range of a compatible RFID reader, the reader generates a 13.56 MHz electromagnetic field. The embedded antenna inside the card captures this energy and powers the RFID chip. The chip then transmits its unique identification number (UID) and stored data back to the reader using radio frequency signals. The reader processes this information and sends it to a computer, microcontroller, or access control system for authentication or data processing.

Most RFID smart cards provide read/write memory, allowing users to store and update information such as identification numbers, user credentials, attendance records, access permissions, or application-specific data. Data security is enhanced through authentication and encryption features supported by compatible RFID chips.

The RFID Smart Card is compatible with 13.56 MHz RFID readers and NFC modules, including:

• PN532 NFC Module

• RC522 RFID Module

• ACR122U RFID Reader

• NFC-enabled smartphones (for supported card types)

• Industrial RFID readers

• Access control terminals

The cards are also compatible with popular development platforms such as Arduino Uno, Arduino Nano, Arduino Mega, ESP32, ESP8266, Raspberry Pi, STM32, PIC, and AVR when used with suitable RFID reader modules.

Typical features of the RFID Smart Card include:

• Contactless operation

• 13.56 MHz operating frequency

• Unique factory-programmed UID

• Fast data communication

• Read and write capability (depending on chip type)

• No internal battery required

• Long reading life

• Waterproof PVC construction

• Durable and reusable design

The typical reading distance is 2 to 10 cm, depending on the RFID reader, antenna size, operating environment, and card type.

The applications of the RFID Smart Card include access control systems, employee attendance systems, student identification, hotel key cards, smart parking systems, public transportation ticketing, library management, membership cards, inventory management, asset tracking, authentication systems, smart home automation, IoT devices, robotics, laboratory experiments, educational electronics, prototype development, and DIY electronics projects.

The advantages of the RFID Smart Card include contactless operation, fast identification, durable PVC construction, reusable design, waterproof surface, no battery requirement, secure authentication, reliable data communication, easy integration with RFID systems, compatibility with various RFID readers and microcontrollers, low maintenance, and long operational life.

In conclusion, the RFID Smart Card (10 Pcs) is a reliable and durable contactless identification solution for RFID-based systems. Its secure wireless communication, reusable design, compatibility with standard 13.56 MHz RFID readers, and support for access control, attendance, automation, and embedded applications make it an excellent choice for educational projects, industrial systems, IoT devices, security applications, and electronics development.
