# What is a Non-Fungible Token (NFT)?
{% hint style="info" %}
**Good to know :** In this article, we'll break down what an NFT is.
{% endhint %}
**Non-Fungible Tokens (NFTs)** are unique digital items with blockchain-managed ownership. There are many kinds and applications of NFTs - but before we dive into the details, let's learn about a key term: **fungibility.**
### What is fungibility?
If something is **fungible**, it is easily exchanged with something of equal value. Don't get overwhelmed by the idea of **fungibility;** it's just the ability of a good or item to be interchanged with other individual goods or items of the same type.
A simple comparison of fungible, semi-fungible, and non-fungible items is pictured below.

Fungible items like a dollar bill, gold - even cryptocurrencies like Bitcoin and Ethereum - can be substituted with one another without losing value. They are **fungible**.
### Non-fungibility and NFTs
If something is **non-fungible**, it means that it cannot be replaced. It represents something unique in value - and that's what an NFT is!
The **token** part of **Non-Fungible Token** refers to a digital certificate stored on a publicly verifiable distributed database, also known as a blockchain.
The information on this digital certificate, also known as a smart contract, makes each NFT unique. No two NFTs can be swapped, and this makes them **non-fungible**. Examples of NFTs include digital art, collectibles, virtual reality items, crypto domain names, ownership records for physical items, and more!
### Types of NFTs
There is only one type of NFT currently supported on NumisArt.
* **1/1 NFTs** - known as **BEP-721** tokens
**1/1 NFTs**, known by their token standard as **BEP-721** on BSC, are the classic definition of Non-Fungible Token's that we've described above. Each NFT is unique and distinct from other NFTs.
