A Simple, Powerful NFC Emulator

The Flask is a small, thoughtfully designed NFC and Bluetooth-enabled device that emulates NTAG215 NFC tags. Whether you're managing key fobs, access cards, or even Amiibo, the Flask makes it easy to carry up to 85 tags in one neat little device.

We built it to be reliable, practical, and easy to use—because we wanted a tool like this ourselves.

What It Can Do

NTAG215 Emulation

How It Works

Using the Flask is straightforward. You upload your tags through the Flask apps—available for mobile, web, and desktop. Once your tags are loaded, you can select the one you want from the device itself or through the app. When scanned, the Flask behaves just like the original tag.

We’ve tried to make the experience as seamless and friendly as possible.

The Flask is currently priced at £66 (roughly $82), and you can find it in our online shop.
