C. Instructions for use:
a) First, check if your smartphone has NFC function. It can usually be found in the system settings. If you can’t find the relevant option, please contact the manufacturer’s after-sales support, or search Google for whether the smartphone model has NFC function and confirm its NFC area.
b) If your smartphone has NFC function, please turn on the NFC switch, search for NFC-applicable software in your app store, then download and install them.
