    • Check Device Settings: You can also check your device’s settings to see if it has NFC capabilities. Go to Settings > Connected Devices > NFC or Settings > Wireless & Networks > NFC. If you see an NFC option, your device supports NFC.
    • Use NFC Checker App: You can download an NFC checker app from the Google Play Store. These apps can detect whether your device has an NFC chip and whether it is enabled.
  6. Future Trends:
    • Increasing Adoption: The adoption of NFC is expected to continue to increase in the coming years, as more merchants and service providers support mobile payments and other NFC-based services.
    • Standard Feature: It is possible that NFC will eventually become a standard feature on all Android devices, as the cost of including NFC decreases and the demand for NFC-based services increases.
