TiMER JKCM R3 Smart NFC Multifunctional Ring 2016 for Android and Windows Phones, Size 8

Can't use rfid. Not as simple as an app.

Great ring.. really pleased with this. Don’t expect to make calls etc but for transferring small pieces of info like text, businesses cards or social media links it’s awesome

Great Jackom Smart Ring Works with NFC Device But As you May not want to be mislead it is not an Countless Card Payment Ring but is For The Sole Use of Many NFC Devices That Have This Chipped Ring Data Store And Share Information Is as Well Water Proof.
