Duinotech Arduino Compatible RFID Read and Write Module (MiFare)

You want contactless card or fob access in your project — a door lock, a badge-in system, a data tag reader — but you're not starting from scratch. This module reads and writes MiFare-type tags over SPI, so it plugs into your Arduino and you're coding logic, not building radio hardware. Comes with one credit-card-style tag and one key-fob tag so you can test read and write the same afternoon

• Reads and writes MiFare-type RFID tags — not just read-only
• SPI communications protocol for straightforward Arduino integration
• Includes one credit-card-style tag and one key-fob tag, both readable and writable
• MiFare protocol support for standard contactless security applications
• Compact module format for breadboard or PCB projects
