From sales network to doorstep: the pipeline for 3D-printed NFC displays

Producing hundreds of personalised pieces without wrong logos, unprintable text or duplicates, and tracking them until delivery. Before, it was all done by hand.

• Web app for the sales network, back office and workshop, with Google Places import and duplicate detection
• Python pipeline: logo search, printable reconstruction, preview with verified QR code and printability score
• Automatic 3MF files and print plates for the workshop’s printers
• Business confirmation through a public page and WhatsApp
• Packing with labels and NFC tag writing from a smartphone
• Shipping and tracking integrated with Sendcloud, keyboard-driven approval panel

Claude models write the logo brief and read the smallest text; the logo is redrawn as a vector or an image and measured against how it really prints. An agent checks every hour that the logo truly belongs to the business, finds it if missing and makes it printable. Automatic AI stays off until someone turns it on.

Three roles, bcrypt passwords and sessions revoked on password change, credentials encrypted with AES-256-GCM, HMAC-signed links. Releases only run if automated checks pass, using an SSH key that can run a single command.
