Tips:
1, this NFC function (NFC processor: Fudanwei F08S, IC card, no battery power required, not same as the nfc function of smart watch) only for smart access control of the smart lock. still not avaible for wireless payment.
2, to input the information to your smart ring , you need to download one NFC assistant app. (normally can input text information , URL links, telephone number , name card, Bluetooth/Wifi network , locations , open app), to use this function, you need to make sure that your smartphone also supports NFC functions (now still can not write nfc card information to this ring)
3: This size is based on American ring standard.
