13.56MHz FM1108 1K RFID Key Fob keychain Compatible MIFARE S50 ISO14443A Access Control Card Identification and Authentication


The tag contains a NXP S50 chip and an antenna, and is passively powered by the reader/writer when placed a couple inches away.
These use the S50 chipset, which used to be the 'classic' NFC chipset. In ~2014, the NFC forum decided not to support this chipset anymore, so newer phones do not support the MiFare classic. This only matters if you're trying to use this tag with a phone/tablet.
