Tutorial: RFID Keyring Tag (13.56MHz) + Arduino - Read UID, Read/Write Blocks, Access Control Patterns
This tutorial is a comprehensive, practical guide to using a <strong>13.56MHz RFID keyring tag</strong> (Leobot Product #564) with Arduino projects. You’ll learn what hardware you need, how to wire a reader module, how to read a tag UID, how memory is typically structured, how to read/write data blocks, and how to build robust access-control style logic (relay unlock, attendance logging, asset checkout, etc.).
