Description
This app allows you to read and write Creality compatible MIFARE Classic 1k RFID tags, allowing you to use the RFID features of the Creality K2 Plus printers and CFS with any brand of filament. Simply create 2 tags for each roll of filament (one on each side) and use as you would Creality RFID Filament.

The app can now read and write encrypted tags so you can re-spool and reuse your Creality spools and tags for any filament!

Note: These tags might not work the same as Creality tags, and Creality can remove the compatibility at any time.


This app is a fork of the MIFARE Classic Tool by Ikarus23 - https://play.google.com/store/apps/details?id=de.syss.MifareClassicTool&hl=en_US

Recent changes:
- Support for reading and writing Encrypted tags. Reuse your Creality spools and tags! Quick tag encryption with no input - just Read and Write.
- Updated UI
- Changed Color prefix to 0 to match Creality tags and moved this prefix to Advanced. Note: This value isn't updated on tag Reads to standardize on 0.
- Added the Sector 1 Key used by the last read or written tag. This is just for reference, this text field is not used for anything else.

Comments on RFID for CFS for Android

★★★★★ Patrick H · Jan 10, 2025
This app works great for making custom tags. Makes it, so I don't have to manually set each spool. I only wish it could do Bambi spools as well.
★★★★★ Max Wood · Dec 30, 2024
Works very well! Easy to use app with clear instructions. The CFS doesn't even recognize that the RFID tags aren't genuine!
★★★★★ Pete Van Rooy · Feb 11, 2025
Works great except I can't change color it crashes the app every time I try and change color. Please let me know what I'm doing wrong.
★☆☆☆☆ dANo · Jan 5, 2025
Doesn't work. The printer doesn't read the data on the taps properly. Just comes up with a question mark for the filament.
