About this app

Custom Tag Management for Creality Printers.

Take full control of your Creality Filament System (CFS). Cfs RFID is a powerful, open-source utility designed to program MiFare Classic 1k RFID tags, allowing your Creality printer to instantly recognize any filament brand, type, or color.

Key Features

Custom Filament Programming:
* Create and write custom filament profiles (brands and types) to RFID tags that your printer can read.

Advanced Color Matching:
* Visual Picker: Find the perfect shade using an intuitive color wheel.
* Presets: Choose from a library of standard manufacturer colors.
* Camera Capture: Take a photo of your filament and pick the color directly from the image.

Printer Management:
* Easily add, manage, and sync with multiple Creality RFID-enabled printers.

Database Protection:
* Edit existing Creality filament settings with an "Prevent DB updates" feature that prevents the printer from reverting your custom tweaks during background updates.

Spoolman Integration:
* Seamlessly add and track your physical inventory by syncing your spools directly with your Spoolman database.

Advanced Tag Tools:
* Dedicated functions to format tags and perform raw memory reads for deep troubleshooting.

Sync & Backup:
* Update your local database from Creality Cloud or the printer itself while preserving your custom data. Includes Import/Export functions to move your library to other devices.

Open Source & Transparent:
* Cfs RFID is built for the community. View the source code, contribute, or report issues on our GitHub repository.

Ratings and reviews

edited due to user error..... first time it worked the. it wouldn't work after many of many trys nothing then I click dont update data base everything updated perfectly and all my filaments uploaded to printer!!!! works good for programming rfid nicely but I can't update the printer database i can download it and its basic stock but when I try to upload my profiles it'll say it uploaded reboot the printer but nothing changes at all out won't update the database

I love the product - but I started to add all of my rolls in - and just noticed that there are options for UPLOAD / DOWNLOAD Printer database & Export & Import App Database - is there a user manual document somewhere? Nothing needs to be fancy - just a general "Heads-Up" to what the options do.... Thanks!

11/10/25: I apologize. I thought this was your other app that handles both. I love this app and have never had any problems at all. 10/30/25 update broke the ability to write to tags for Anycubic. It will read the tag, but won't write
