This blank 13.56 MHz RFID/NFC clear tag contains an NTAG203 chip with 144 bytes of writable EEPROM storage. The compact transparent disc form factor is commonly used for laundry tracking, asset identification, and general-purpose NFC tagging. The 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.
