RFID Tag with Keychain 13.56MHz – Mifare Classic 1k Chip

From the shop's description

RFID Tag with Keychain 13.56MHz – Mifare Classic 1k Chip This device is a passive RFID tag operating at the 13.56 MHz frequency, built around the widely adopted MIFARE Classic 1K chip. It functions without an internal battery, instead being powered entirely by the electromagnetic field emitted from a compatible RFID reader when brought into close proximity. This core technology enables seamless and contactless data exchange, making it a simple and effective tool for identification and data storage. Housed within a durable keychain form factor, the tag is designed for everyday convenience and ruggedness. The keychain design transforms the tag from a simple chip into a personal accessory that is easy to carry, attach to key rings, and highly resistant to loss. This physical robustness ensures it can withstand the physical demands of daily use, making it suitable for a wide range of environments and applications. At its heart, the MIFARE Classic 1K chip provides 1 kilobyte of EEPROM memory, which is divided into sectors and blocks secured with a customizable authentication system. This memory structure allows for flexible data storage, from simple identification numbers to more complex value-based systems, supporting read and write operations to manage information dynamically for various use cases. Features: Contactless communication and power. Durable and portable keychain form factor. Pre-programmed with a unique, unchangeable ID (UID). Rewritable data storage on user memory blocks. Compatible with all MIFARE Classic and NFC-enabled readers.
