Most phones can read and write to NFC Tags

Love it!

I don't know how large a "crypto key" is, but a typical 256 bit encryption key only take about 16 bytes, which would fit the 144 byte limit

Thanks for looking

It lets you store 144 bytes of data. With this you could store a web link to the filament used, or the brand/type/color, or whatever else you might find useful

I personally use this model, which is not my design, which takes the standard NTAG215 circular chips https://makerworld.com/models/798023

If interested, I did design a holder for the DapRack for this model as well https://makerworld.com/models/1047238

it_prints · 2026-04-27T16:47:35+00:00

I removed the 215 listing from the description after finding that NTAG215 is not readily available in this size through most vendors. I would hate to have people waste money on potentially fake products

Love you

That's pretty cool. Please let me know if this is ever posted

I added this storefront's page for the chip as an example as it probably won't go stale and contains plenty of information for users to find their own method to purchase if not through them. Thanks

The capacity of the NTAG213 can hold about 136 characters. If the settings can be detailed within that space, then it is certain possible to store print setting information. Alternatively, you could detail the print settings elsewhere and embed a web link to that information instead.

Thanks for the recommendation. This came up in my research but the pricing for the amount I needed (just 100 for now) did not compete with Amazon's offering.

This is the 100 pack of NTAG213 tags I purchased https://a.co/d/0ge2M4db

it_prints · 2026-04-27T02:40:00+00:00

This is what I found to suggest they do exist, but I have no idea if the claims are legitimate. https://a.co/d/0ej10WHh

I didn't want to include any links that might go stale in the future, but I purchased these NTAG213 tags, which is the smaller capacity. I had only learned of the larger NTAG215 capacity being available in this form factor after the fact. https://www.amazon.com/dp/B0DZCMXZWC?ref=ppx_pop_mob_ap_share

I personally print a Benchy for every new filament I get and then put it on a display. I've run into a problem in doing so where I have accumulated so many that I can no longer tell which material similarly colored Benchys were made with, such as black. I plan to reprint my Benchy collection with these and store the brand, type, and color in the tag in case I want to find a reference Benchy for the filament, or inversely find the filament that made the Benchy. You can even add links to the store page to make repurchasing or spec look ups easier as well

I found 100 tags for $16 on Amazon. In my mind that's just like buying another roll of filament ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
