A variety of shapes and sizes are offered for NFC tag. RFID paper stickers can be one-sided or both sides printing.
NFC Tags surfaces have water-resistant paper, soft/hard PVC and PET. All stickers are water-resistant and durable.
The NFC tag is a passive device with no power of its own. Accordingly when one is used, the users touches an NFC enabled device onto the tag. A small amount of power is taken by the NFC tag from the reader/writer to power the tag electronics.
