What is the Flask?
The Flask is an nfc tag emulator. You can store up to 75 tags including keyring fobs, keycards and amiibos. Any NTAG215 type NFC tag. Use them just like the original.
How does it work?
It's easy. You add tags to the Flask using the web interface (flask.run). The web interface is only needed to add tags. The Flask can be used offline and is simply scanned like an NFC tag. You can nagivate between tags using the buttons on the flask itself. The Flask holds 75 tags.
How do you add tags?
You use the web interface to add tags, found here. It requires a bluetooth capable device. If you ever forget the address, it’s on the back of the flask!
There are two ways to add a tab. One is to upload an NFC Tag backup, typically a .bin file. The second is to create a blank tag and then use an NFC writer to write the tag you want. e.g. using an iOS or Android app.
There are plenty of guides for doing this. Uploading the tag directly to the Flask just removes the step of having to use an NFC writer. But the option is there for those that want to.
Ways to add a tag through the web interface
You will need the following to be able to use the Flask:
- PC, laptop or Mac with the latest Chrome
- Bluetooth capable PC, laptop or Mac. You can use a Bluetooth dongle if needed.
Where do I get the amiibo tags?
Any Amiibo tag you use should be a backup of one you own as they are copyrighted. I can't supply any links or locations for tags uploaded by other people.
The Flask supports both 540 and 572 byte tag backups.
Googling should help you find how to back your tags up, a lot of people store theirs in Google Drive for access on the go. For an idea how to do this, google “Google Drive amiibo”.
