NTAG203 (13.56MHz RFID/NFC) Clear Keychain Fob
100 units available with a short lead time.
A clear 13.56 MHz RFID/NFC keychain fob with an NTAG203 chip. Commonly used for transit passes, information sharing, and contactless identification, this tag contains a small RFID chip and antenna that is passively powered by a reader when placed a few centimetres away.
The NTAG203 is a "Type 2" NFC tag compatible with virtually any smartphone that supports NFC. Unlike Classic 1K (MiFare S50) cards, NTAG chips avoid NXP patent licensing issues, making them more universally compatible and more secure.
