Connectivity
What is NFC and what is it for?
NFC (near field communication) is a very short range wireless link: it only works when two devices are a few centimeters apart. It is used to pay by holding a watch or phone near a terminal, to pair accessories with a tap and to read tags. It carries little data, but almost instantly.
What it is used for
The best known use is contactless payment: the watch or phone acts as a card when held near the terminal. It is also used to pair headphones or speakers with a tap, instead of searching the Bluetooth menu, and to read NFC tags that open a link or trigger an action.
The very short range is deliberate: it forces you to bring the devices together on purpose, which lowers the risk of accidental connections.
Having NFC does not guarantee you can pay
Paying takes three things besides the chip: a payment app compatible with the device, that app operating in your country, and your bank allowing you to add the card. If one is missing, the NFC is there but payment does not work.
On budget watches, NFC often serves only the watch's own functions, such as access cards, and not payments. Before buying for that feature, confirm with your bank which payment apps it supports.
What to check before you buy
- If you want it for paying, check the payment app and your bank first, not just that the page says NFC.
- For tap to pair, both devices must have NFC.
- If you will not use it, do not make it a deciding factor: every other function stays the same.

Frequently asked questions
No. NFC works over a few centimeters and carries very little data; Bluetooth reaches several meters and is used for audio and continuous syncing. Sometimes NFC only starts the pairing and Bluetooth does the rest.
