Bambu Tag: write to your tags

The RFID tag on an empty Bambu Lab spool is still perfectly usable. Bambu Tag lets you read it, then turn it into a universal NFC tag that any phone can read, with no app needed.

READ A BAMBU LAB TAG
• Hold the tag to your phone: the UID and all 16 sectors are shown.
• For a Bambu tag, the filament card is decoded: material, colour, nominal weight and length, temperatures, production date.
• Reading works offline and stays on your phone.

WRITE TO A TAG, SIX USES
• URL: the phone opens the page when scanned.
• Text: the message is displayed.
• Wi-Fi: the phone offers to join the network. One button fills in the network you are on.
• Business card (vCard): the phone offers "Add to contacts".
• GPS position: the maps app opens at the chosen spot (coordinates copied from Maps, or your current position).
• App: launches the app of your choice, or opens its Play Store page if it is not installed.

Ideas: a Wi-Fi sticker for guests, a contact tag on your workbench, a link to your printer's profile, a shortcut to your slicer app, a GPS meeting point.

BUILT TO BE RELIABLE
• What you write is read back and compared before success is announced.
• A counter shows the space used on the tag (about 700 bytes maximum).
• A confirmation is required before any write.
• The "Already used" list remembers your content so you can reload or delete it. Wi-Fi passwords are stored encrypted.
• English and French interface, light or dark theme.

BEFORE YOU START
• Writing to a Bambu Lab tag is irreversible: its keys are replaced, the printer no longer recognises it and the filament data is lost. Use it only on tags from empty spools.
• Works with Mifare Classic 1K tags only.
• Requires an Android phone with NFC and an NXP chip (low-level Mifare Classic access). Phones with another chip maker may not work.
• iPhones cannot read Mifare Classic: a tag written with this app will not be read by an iPhone.

PRIVACY
• No account, nothing sent to a server: your content stays on the phone.
• Location is requested only if you use "Current Wi-Fi" or "Current position" (Android requires it to get the network name).
• Google AdMob ads are shown. In the European Economic Area, the UK and Switzerland, a consent form is offered and can be changed at any time in settings.
