For FoloToy AI Passport · macOS

Your name badge is also your microphone.

Hold a button, speak, and the words appear on your Mac. BadgeMic works with the dictation tool you already use, and doubles as a name badge with your contact QR code.

How it works

The badge does one thing well: it listens while you hold OK. Everything else happens on your Mac, in apps you choose.

Hold OK and talk

The badge records with its own microphone and compresses your voice with Opus.

Bluetooth to BadgeMic

An encrypted, paired Bluetooth LE link carries the audio to the BadgeMic app. No Wi-Fi, no account.

Your dictation tool types

BadgeMic plays the audio into a virtual microphone and holds your tool's hotkey. Release OK and the text lands where you're typing.

One badge, two jobs

A name badge when you're meeting people, a microphone when you're writing.

Name card and QR code

Design a portrait name card on your Mac and add a QR code with your vCard (phone, email, website) or any link.

Works with your dictation tool

Parroting, Doubao, macOS Dictation or anything with a hotkey. Profiles for hold-to-talk and press-to-toggle.

Buttons you can program

Map UP and DOWN short or long presses to shortcuts, Return, text snippets, Shortcuts, opening an app, or turning the screen off.

Screen on your terms

Choose when it dims and sleeps, keep it always on at an event, or hold a button to turn it off instantly.

Private by design

Audio only travels to your own Mac over a paired link. BadgeMic itself never uploads anything.

Open source

Firmware, Mac app and virtual microphone driver are MIT licensed, built on FoloToy's open AI Passport template.

Get started in four steps

About fifteen minutes. The full guide, with commands, is in the README.

Back up and flash

Save a copy of the badge's original firmware, then flash BadgeMic with esptool over USB-C.

Install the app

Open the DMG, then install the virtual microphone and allow Accessibility from inside the app.

Pair and pick a tool

Enter the 6-digit code shown on the badge, choose your dictation tool's hotkey, and set its microphone to BadgeMic Microphone.

Make your badge

Fill in your name and contact details, add a photo, and upload. Tap OK to flip between pages.

Questions

Does it work with iPhone or Windows?

Not yet. BadgeMic is a Mac app; the badge talks to it over Bluetooth LE.

Does the badge need Wi-Fi or an account?

No. It only pairs with your Mac. There is no cloud service behind BadgeMic.

Which dictation tools work?

Any tool that starts listening on a hotkey and lets you choose its microphone. Many tools have their own microphone setting, so pick BadgeMic Microphone there.

Can I go back to the official firmware?

Yes. Write your backup back to the badge, or follow FoloToy's restore guide. Never run erase_flash: it removes the device identity.

Is this an official FoloToy product?

No. It is a community project built on FoloToy's open-source template and is not supported by FoloToy.

What about the NFC tag on the back?

It is a separate chip. Write any link to it, such as your LINE or LinkedIn profile, with a phone app like NFC Tools. Don't lock it.
