Similarly, you may ask, what does NFC do on my phone?

NFC stands for Near Field Communication and lets you quickly share various files with other mobile devices, make payments via services like Google Pay, and more. You can program an NFC tag to perform tasks such as open a web page, configure phone settings, or even send a text just by tapping the device against the tag.

Furthermore, what is card emulation mode in NFC? Host card emulation is the ability for near field communication (NFC) information transfer to happen between a terminal configured to exchange NFC radio information with an NFC card and a mobile device application configured to act or pretend to emulate the functional responses of an NFC card.
