One filament manager, every NFC standard
Most NFC tools only speak one brand's language. SimplyPrint reads and writes Bambu Lab, Creality CFS, Prusa OpenPrintTag, OpenSpool and OpenTag from a single inventory - so a mixed fleet of printers and filament all live in one place. And because usage is tracked automatically from G-code anyway, NFC is a convenience, never a requirement.
What NFC filament tracking is
An NFC tag is a small chip stuck to a spool that stores its identity - brand, material, color and remaining weight. Tap it with a phone, browser or USB reader and SimplyPrint pulls up (or creates) the matching spool instantly. Write to the tag and the data travels with the spool, so any printer or platform that reads it knows what's loaded. It's the fastest way to identify a spool and keep its record in sync.
Read an NFC tag from your phone, browser or desktop reader
However you scan - the mobile app, Web NFC right in your browser, or a desktop USB reader - tapping a tagged spool loads its details in a second.
Every NFC filament standard, side by side
Pick your printer's ecosystem, or mix and match across all of them. SimplyPrint reads and writes each one from the same inventory.
Three ways to read and write a tag
Use whatever you already have. Each method reads and writes to the same SimplyPrint inventory.
How to create an NFC tag for a spool
For the writable standards, encoding a spool's data onto a tag takes three steps in SimplyPrint.
No vendor lock-in
Other ecosystems only recognize their own tags. SimplyPrint treats every standard as a first-class citizen, so a Bambu spool, a Prusament with OpenPrintTag and a DIY OpenSpool tag all sit in the same inventory and tracked the same way. Assigning an NFC ID that already belongs to another spool de-conflicts automatically, so you never end up with two spools claiming the same tag.
You don't even need NFC
NFC makes a spool faster to identify, but it's never required. SimplyPrint deducts filament usage automatically from the G-code of every print you start, whether or not the spool carries a tag. Add NFC where it helps, skip it where it doesn't - your inventory stays accurate regardless.
