How to check Android smartphone has NFC enabled or not?

Card emulation mode: This mode allows NFC devices to act itself as an NFC card so that an external NFC reader can access it.

P2P (Pear-to-Pear) Mode: This mode gives the facility to NFC device for exchanging information with other NFC devices.

Reader/Writer Mode: This mode allows NFC devices to read and/or write passive NFC tags.

There are three different types of operational modes performed by Android-powered devices with NFC. The rate and speed of data transfer via NFC is good for transferring songs, pictures, and videos. The frequency rate of data transfer across NFC is 13.56 megahertz, and this data is sent either by 106, 212, or 424 kilobits per second. The data which is stored on a tag can be written in different formats. These tags are a combination of various sets of complexities. The data are sent on the basis of tags between devices.

The NFC sends data through electromagnetic induction between two Android-powered devices. Like Wi-Fi and Bluetooth and all other modes of wireless signals, the NFC works over the radio wave principle to send data.

It is a small range of technology up to 4cm or even less to share data between two Android devices or between NFC tags and Android-powered devices. The term NFC refers to Near Field Communication that establishes a wireless communication network between two supported devices to communicate each other.
