Nintendo ? I don't know.
When you Google "NFC writer/reader", you get a lot of results that point to Nintendo's Product offering.
What I am talking about is a "reader/writer" item you plug on your USB pc. You can then program cards, or little labels that you can use for access control (for example), labels you can use instead of bar-code...
Correct me if I am wrong ... but NFC stands for "near field communication" ... where you transfer information between two devices (usually phones) wirelessly ... so where does the USB plug/connection fit into the equation ?
Perhaps you can point to a website/page of a device supplier that you are interested in.
