## Description

This blank 13.56 MHz RFID/NFC sticker contains an NTAG203 chip with 144 bytes of writable EEPROM storage. The thin adhesive-backed form factor (4 × 2.5 cm) makes it easy to apply to equipment, packaging, shelves, or any smooth surface. The embedded chip and antenna are passively powered — no battery is needed. The NTAG203 is a "Type 2" NFC tag that works with virtually any NFC-enabled smartphone (Android or iPhone) without proprietary licensing issues. Unlike Mifare Classic tags, NTAG-based tags avoid NXP patent restrictions and are supported by all modern phones.
