how to use nfc reader in unity

I’m looking to make a game like skylanders and I’m looking to use my nfc reader to load a tag in unity but I don’t know how to use my reader in unity, does anyone know to get unity to recognize my reader and say display an image.
Thanks, any help would be fantastic.

You’d use the methods in System.IO, much like, say: Reading Serial data in Unity from Android app - Questions & Answers - Unity Discussions
