Implementation notes

  1. 01
    A complete online-to-offline loop

    Users discover nearby series, scan or pay to claim a work, follow pickup progress, and receive the printed piece at the device.

  2. 02
    NFC turns the object into a digital keepsake

    Personal cards, recordings, and public-token sharing extend the physical print into a reusable digital collection.

  3. 03
    Clear product boundaries

    The Mini Program handles discovery, collection, pickup, and presentation; AI generation and printing run on the coordinated offline device.
