Instructions for use:
1. First check if your smartphone has an NFC function. It can usually be found in the system settings. If no relevant options are found,
Contact the manufacturers customer service or search Google if the smartphone model has NFC function and confirm the NFC area.
2. If your smartphone has NFC function, turn on the NFC switch, search for the software that applies NFC in your app and download and install it.
3. Start the NFC app and perform the actions according to the instructions.
4. Since NFC is a near-field communication technology, when reading data, make sure to place the top of the ring chip directly next to the NFC area to avoid errors when reading and writing.
