I have been using the 3d printer at nostr:npub1an84q6c03wml5lf0uwcqcr20ydwv0t0lvv0xktlcfs9seattef8sdhz6yg as containers for NFC stickers programming them thru LN Bits to create bearable and wearable spend/receive/sign/connect key tags. Combining the ideas from www.plebtag.com with Nostr identities to form a membership ID badge/wallet/key.

Physical interfacing devices that bypass paper and fiat money systems enabling face to face cash<=>LN satoshi OTC trading with reprogrammed LN vouchers.

I need help scripting the autimation of the many operations I currently am doing manually so this tool becomes scalable. Reach out in my DMs if you have the interest and skills to help with this.
