## Description

A micro-sized NFC/RFID transponder built around the NXP NTAG203 chip operating at 13.56 MHz. Its tiny, flexible form factor makes it ideal for embedding into rings, wearables, keychains, and other compact devices where full-sized NFC tags won't fit. The tag provides 144 bytes of read-write memory and is compatible with PN532-based readers as well as NFC-enabled smartphones and tablets. Due to the small antenna, the tag must be placed very close to the reader for reliable communication.
