Meet the Flask

An NTAG215 NFC Emulator

The Flask is an NFC and Bluetooth enabled piece of hardware that can emulate NTAG215 NFC Tags. It was created to be easy to use and feature rich. You can store up to 85 NTAG215 type tags like key fobs, keycards and Amiibo. Use them just like the original tag by scanning the Flask. You can swap tags at any time, there are no NFC read or write limits. The Flask is a great way to store your tags and use them on the go. It's like a wallet for your tags.

It costs £66 or around $82 after conversion. The latest prices can be found in the shop

How does it work?

You use one of the management apps, either desktop, web, or mobile, to upload tags to the Flask. The management apps connect and transfer tags via Bluetooth.

Once you've uploaded some tags you can select the specific tag on the Flask using the left or right button, or through one of the management apps.

The Flask can then be scanned and will act like the NFC tag selected.

Connect to apps

The Flask is equipped with bluetooth allowing you to connect to it. You can use the web, desktop or mobile apps to manage your Flask.

Web App

The web app allows you to add, delete and create sets of tags that allows tags to be added in bulk.

Mobile Apps

bluupLabs Connect is available for both iOS and Android and is available in both stores. You can connect to your bluuplabs Flask or Slide using bluetooth and manage your NFC Tags. There is also a tag library to store your tags for quick access.

Will there be improvements?

Definitely! I'm improving the Flask software all the time. I've alread added a low battery indicator, full NDEF support, fast NFC reading times and tag sorting since it's release. The Flask software is updated via the any of the apps, they will prompt you to update the firmware when a new version is available.


I've had some reviews of the Flask when it was first launched from a few YouTubers. Full disclosure, I did send a few units out for free but some were purchased by the YouTubers themselves.
