What this card can do

Card Page

Fill in your details and we’ll make a business card web page; then write its link to a tag. Anyone who taps it with a phone sees your card and can save you as a contact. Edit it any time without rewriting the tag. The free version includes 1 card.

AI Usage Level

A program on your computer regularly reports how many AI tokens you used this month. Every 1 million tokens is 1 XP, and you level up from Novice to Apprentice, Mage, Sage… all the way to Legend. It also works out your school from what you do with AI, with class advancements and achievements. Your card only shows level, title, school and XP — never any conversations or files.

AI Guild

Once you join, the company owner and department managers can see your AI level, school and achievements on the guild dashboard (only what your card already shows, no content). Leaving the company removes you automatically.

Guild Board

Colleagues ask questions and share work and screenshots on the board; a helpful reply can be picked as the best answer. Anything inappropriate can be reported or blocked.

Send a Cheer

Anyone viewing your card can send a cheer for your AI work with one tap; cheers sent from the NFC42 app carry the sender’s name.

Numbers only, never content

The reporter on your computer sends only token and usage counts — your prompts, conversations, files and file names never leave.

Frequently asked questions

Does the AI level card cost anything?

The free version includes 1 card page. Subscribe to Business (or join a company in its trial) to make more.

Does it send my conversations or files?

No. The reporter sends only monthly token totals, usage counts by tool and file type, and a device code — never prompts, files or file names.

Which AI tools are supported?

Claude Code on a Mac reports automatically once you paste one command; other AI tools can report monthly token totals through the API. Install it on several computers and the usage adds up.

Can I keep my level private?

Yes. Turn off “Show on Card” on your card and the card page won't show your AI level.
