When I first started embedding NFC (Near Field Communication) inside 3D printed objects mid-print, a Bitcoin “coin” seemed to be the coolest application. However at that time the only use I could find was simply displaying the long wallet address when prompted.

Now, it seems things have progressed and Mycelium Wallet has started adding NFC functions. Here is a reddit post detailing the info and here is a thingiverse listing that adds to the info.
The same user posted these videos:
Bitcoin NFC tags, 3D printed

This is yet another way we can market our Hubs to those who want a cool tech item like this but don’t have a 3D Printer. Spread the word!
Please post your makes or ideas in the comments.

Hi, glad you liked the new video.
Thanks for the idea, I didn’t know about nfc tags until I saw your thingiverse thing page and video. I started to print some too, but especially when I begin to load them with a private key with some millibits I noticed that people really liked them.
I think they’re, enclosed in their 3D printed shell, a great connection from the virtual world of non-phyisical money to the ordinary world where we are accustomed to use cash that is not virtual/fluid at all!
I reckon it’s time to do a proper NFC wallet that supports loading and spending directly via nfc without copypasting 
Print on!

There is a growing number of marketable one-off projects like this that may be useful if collected into a “Market Your Hub” toolbox.
Yet another startup www.3dp4btc.com
I’d love to see more requests to my Hub for NFC 3DP awesomeness…
