FP4. NFC transmission chip
The Fairphone 4 (FP4) has an NFC (Near-Field Communication) chip on the Back cover.
NFC is a wireless technology that enables short-range communication between compatible devices. This technology offers several services:
- You can use it to pair Bluetooth devices that support it in an instant. Hold the Back cover of the Fairphone 4 near the device you want to pair.
- Or - thanks to the support of Google Pay - you can turn your Fairphone into a payment device. You pay with your phone! Hold it with its Back cover near the reader of the card machine.
- NFC technology can also communicate with RFID (Radio-Frequency Identification), in combination with applications that can interpret the RFID data. However, without an app to read out the specific data, the NFC can already help identify if an RFID chip is working or not: when a working RFID chip is identified by the NFC by holding it close to the Back cover, it is confirmed by a sound.
Different apps can use the NFC chip to perform various tasks.
Once you install an app that uses the NFC chip, i.e., a banking app, you must enable the NFC on your Fairphone.
To do so, go to Settings → Connected Devices → Connection Preferences → NFC and tap on the toggle on the side to set it to On (the toggle is green when enabled).
