Detailed Description:

Unlock the power of high-frequency wireless identification with the RFID White Tag, a standard 13.56MHz RFID Card. This versatile card is the ideal companion for popular RFID reader modules like the MFRC522 and is a cornerstone for building a wide range of advanced projects, from secure access control systems and attendance trackers to smart vending machines and more. Unlike simple, low-frequency ID-only tags, this high-frequency card offers a significant advantage: it supports both reading and writing data.

The RFID card is a passive transponder based on the ISO/IEC 14443 Type A protocol. It operates without an internal battery, drawing power from the electromagnetic field of a compatible reader. It typically contains a MIFARE Classic 1K chip, providing a substantial 1K byte (1024 bytes) of EEPROM memory. This memory is organized into 16 sectors and can be modified, allowing you to not only read a unique ID but also store small amounts of data, such as user credentials, balance information, or unique project data, which can be updated as needed.

With its durable, standard credit-card-sized white PVC design, the card is perfect for daily use. Every card contains a unique, unalterable 4- or 7-byte UID that is factory-programmed, ensuring unique identification for every card. When used with a compatible RFID reader and a microcontroller like an Arduino or ESP32, this card allows you to create robust and sophisticated identification and data management systems. Its reusability and durable build make it a cost-effective and reliable choice for developers and hobbyists in Pune, Maharashtra, India, and around the world, enabling a new level of interactive project design.

The RFID White Tag (13.56MHz) is a passive, contactless smart card designed for use with RFID readers like MFRC522. It is built using the ISO14443A protocol and contains a small chip and antenna inside the durable plastic body.

These tags are ideal for identification, authentication, security systems, and IoT applications where wireless tagging is required. The card contains a unique 4/7-byte UID, which can be read using compatible readers, allowing each card to be uniquely identified in your project.

It is a reusable, blank tag that can be written to (if supported by your system), and is durable enough for daily use in offices, schools, hotels, libraries, and more.
