Open, offline, and already adopted
Unlike most open formats, TigerTag isn't waiting on adoption - real brands already ship spools pre-tagged with it, and several printers and slicers read it. The full record (material, colour, temperatures, remaining weight) is written to the chip, so a TigerTag works with no app login and no internet. SimplyPrint writes your own TigerTag tags and reads brand-written ones, all in the same automatically-tracked inventory as your Bambu, Creality and Prusa rolls.
What TigerTag is
TigerTag is an open, vendor-neutral RFID format for filament and resin, published under the GPL-3.0 license. The whole record is written to the chip, so any TigerTag-aware app or device can identify a spool and read its print settings fully offline - no account, no cloud round-trip.
How to use TigerTag with SimplyPrint
Three steps to an open tag your tools can read offline.
Already shipping on real spools
Most open tag formats are still waiting for adoption. TigerTag isn't: brands including eSun, Rosa3D, Sunlu, R3D and Landu already ship spools pre-tagged with it, and printers and slicers like Snapmaker, Bambu Lab, FlashForge, Elegoo and Creality read it. SimplyPrint supports it today, alongside every other standard in the same filament manager.
Reads brand tags too
If a spool arrives pre-tagged from a partner brand - a signed TigerTag+ tag - SimplyPrint reads it the moment you scan it, no manual entry. You can also write your own standard TigerTag tags for any spool you already own, so your whole inventory is identifiable whether the brand tagged it or you did.
Create a TigerTag for any spool
Because TigerTag is an open, vendor-neutral format, you can write one to any spool you own - budget brand, premium roll, or a mystery spool from the shelf - and it carries its own identity wherever it goes. Write it once in SimplyPrint and the spool is recognised on every read.
Read and write TigerTag
Use the SimplyPrint mobile app or the desktop NFC Agent with a USB reader, and the data lands in the same inventory as every other standard you run. TigerTag stores its data as raw chip pages rather than the NDEF format browsers expose, so it isn't written via Web NFC - the app or a desktop reader handles it.
Remaining weight, on the tag
TigerTag has a dedicated field for how much filament is left, so SimplyPrint can write the current remaining weight to the tag, not just the full-spool figure. Once a spool is identified, SimplyPrint also deducts usage automatically from the G-code of every print - so the numbers stay right without a scale.
