Instructions for use: 1. First, check whether your smartphone has NFC function. It can usually be found in the system settings. If the relevant option is not found, please contact the manufacturer’s after-sales support, or if the smartphone model has NFC function, search and confirm its NFC area on Google. 2. If your smartphone has NFC function, please turn on the NFC switch, search for NFC-applied software in the app store, download and install them. 3. Start NFC APP and follow the instructions. 4. As NFC is a near-field communication technology, when reading any data, please make sure to place the top of the ring chip close to the NFC area to avoid reading and writing failures.
