NFC tags for QIDI Box in SimplyPrint

Got a QIDI printer with a QIDI Box? SimplyPrint lets you read and write NFC tags that work with your QIDI Box - whether you're using official QIDI filament or want to make any filament brand work with your setup.

This article covers everything about using QIDI-compatible NFC tags with SimplyPrint. For a general introduction to NFC in 3D printing, hardware options, and step-by-step guides, see our main NFC article.

NFC support in SimplyPrint

SimplyPrint has deep NFC integration across our entire platform - both the web panel and mobile apps for iOS and Android. We support reading and writing NFC tags in multiple formats, allowing you to work with filament from various brands and make your spools work with different printer ecosystems.

What you can do with NFC in SimplyPrint:

  • Read NFC tags to instantly identify spools and see their details
  • Write NFC tags in various formats - QIDI, Creality, Anycubic, OpenPrintTag, OpenSpool, OpenTag, and more
  • Link physical spools to their "digital twin" in your filament inventory
  • Quickly assign spools to printers by scanning instead of scrolling through lists

How you can read and write NFC:

  • Mobile apps (iOS & Android) - most phones have built-in NFC, making this the easiest method
  • Desktop USB readers - for those who prefer working from their computer
  • Web NFC - some browsers support NFC directly (Android Chrome, for example)

Not all methods work with all tag types though - and that's where it gets a bit tricky. QIDI uses a specific tag format (MIFARE Classic) that has some limitations, which we'll cover below.

For the full breakdown of hardware options, supported methods, and step-by-step guides, check out our main NFC article.

What can SimplyPrint do with QIDI NFC tags?

With SimplyPrint, you can:

  1. Write QIDI-compatible NFC tags for any filament - stick them on your spools and your QIDI Box will recognize them, even if they're from Polymaker, eSUN, Prusament, or any other brand
  2. Link existing QIDI tags to your SimplyPrint inventory - if you buy QIDI filament that already has NFC tags, connect them to your digital spool library
  3. Quickly identify spools by scanning - no more guessing which spool is which when you have 50 of them

For hardware requirements and step-by-step instructions on reading/writing NFC tags, see our NFC hardware & methods guide.

Important: What SimplyPrint can and can't do with QIDI

Before diving deeper, here's what you need to know about the integration:

What works great

Your QIDI Box will recognize the tags - When you write QIDI-format tags via SimplyPrint, your QIDI Box reads them just like official QIDI filament. The printer knows the material type and color and can apply the right settings.

Fast spool identification - Scan any tagged spool with your phone (Android) or desktop reader to instantly see which spool it is in SimplyPrint. Way faster than scrolling through your inventory.

What doesn't work (yet)

No automatic sync from the printer - Unlike Bambu Lab AMS, QIDI printers don't tell SimplyPrint what filament is loaded. When you put a spool in your QIDI Box, SimplyPrint won't automatically know about it.

You'll need to manually assign spools - After loading filament, you'll still need to tell SimplyPrint which spool is on which printer. The good news? With NFC tags, this takes seconds: scan the tag, tap assign, done.

About the QIDI standard

Now let's get into the details of how QIDI NFC tags work.

The QIDI material standard is a proprietary format developed by QIDI Technology for their QIDI Box. It's one of the simpler NFC formats out there - it stores just the basics - but it gets the job done.

Who made it?

QIDI Technology - the Chinese 3D printer manufacturer known for their enclosed printers like the X-Max, X-Plus, and Q1 series.

Official documentation

QIDI has published their RFID specification on their wiki:

There's also a community reverse-engineered implementation:

What printers use this?

Any QIDI printer that supports the QIDI Box multi-material system.

What data does a QIDI tag store?

The QIDI format is simple - it only stores three pieces of information:

What's storedDescription
Material typeWhich material it is (PLA, PETG, ABS, etc.)
ColorThe filament color
ManufacturerWhether it's QIDI-branded or third-party filament

That's it! No weight tracking, no additional notes. It's basic, but it's enough for the QIDI Box to know what filament you're using.

Do I need to worry about material and color matching?

Nope! SimplyPrint handles all of this for you. When you write a QIDI tag, we automatically find the best matching material type and color from QIDI's supported options.

There are some limitations though - QIDI only supports around 35 material types and 24 specific colors. If you're using something exotic, we'll pick the closest match. For most common filaments (PLA, PETG, ABS, TPU, etc.) it works great.

Curious what materials and colors QIDI actually supports? Check out the Advanced: Supported materials and colors section at the bottom of this article.

What NFC tags does it use?

The QIDI standard only works with MIFARE Classic 1K tags. This is important - you can't just buy any NFC tag and expect it to work!

There are many different types of NFC tags out there, and QIDI picked one specific type for their system. If you buy the wrong kind, your QIDI Box simply won't recognize it.

Where to buy compatible tags

Look for "MIFARE Classic 1K" tags:

Make sure the listing says "MIFARE Classic 1K" specifically. Tags labeled "NTAG215", "NTAG216", or "MIFARE Ultralight" will not work with QIDI.

Compatible hardware

Because QIDI uses MIFARE Classic tags, not all devices can read and write them:

MethodReadWriteNotes
SimplyPrint app (Android)Full support
SimplyPrint app (iOS)iOS can't handle MIFARE Classic
Desktop USB readerRequires ACS reader + NFC Agent
Web NFC (browser)Web NFC doesn't support MIFARE Classic

Why write QIDI tags via SimplyPrint?

So why bother writing QIDI tags through SimplyPrint instead of some other tool?

1. Use any filament brand with QIDI Box

The main benefit: you can make any filament work with your QIDI Box. Got a great deal on some eSUN PETG? Write a QIDI tag for it. Want to use that fancy Prusament Silk? Write a QIDI tag for it. Your QIDI Box doesn't care where the filament came from - it just reads the tag.

2. Keep your inventory in sync

When you write tags via SimplyPrint, the spool is already in your inventory. The tag gets linked automatically, so there's no disconnect between your physical spools and your digital inventory.

3. Smart material matching

SimplyPrint automatically maps your spool's material type and color to the closest QIDI equivalents. We handle all the translation between "eSUN PETG Solid Orange" and "QIDI material code 39, color code 23" behind the scenes.

4. Consistent workflow

Whether you're writing tags for QIDI, Creality CFS, Anycubic ACE, or any other standard, the process in SimplyPrint is the same. Learn it once, use it everywhere.

Limitations of the QIDI format

The QIDI format is functional but limited compared to some other standards:

LimitationWhat it means
Limited colorsOnly 24 colors to choose from - your exact shade might not be available
Limited materials~35 material types - exotic materials might not have a match
No weight trackingThe tag can't store how much filament is left
No custom notesCan't add batch numbers or other metadata
Specific tag typeOnly works with MIFARE Classic 1K tags
No iOS supportiPhones and iPads can't read or write these tags

If you need more flexibility - like exact color matching, weight tracking, or iOS support - consider using a community standard like OpenSpool or OpenTag for your non-QIDI filament. Your QIDI Box won't read those, but your SimplyPrint inventory will work great with them.
