contactless payment solutions, such as Apple Pay. It can also facilitate the activation and use of digital transit tickets, like those for your local transportation service.
The main limitation of NFC, which is also the reason it is generally viewed as a more secure transmission method, is that the wireless range is quite short. Thus, you need to be in close proximity (within touching distance) for it to function. Additionally, you can configure a setting that permits tag scanning only when your phone is unlocked through a “Require device unlock for NFC” feature for enhanced security (this setting is dependent on the OEM).
However, if distance becomes an issue and you lack access to your phone, then you might find it difficult to take advantage of functionalities like scanning tags or sharing your Wi-Fi information using this feature. These are useful functionalities, but they are not the sole capabilities of the NFC reader embedded in your smartphone. It appears that there are three operational modes for NFC: card emulation mode, reader and writer mode, and peer-to-peer mode.
