COMMUNITY-READY, NOT A REPOSITORY DUMP
Everything needed
to learn and ship.
This free release includes a reusable generator, example configuration, setup guide, automated QR and contact validation, and this public learning page. It shares the utility without exposing Anthem’s personal website repository.
THE PATTERN
Three files.
One clean handoff.
Generate locally
The utility creates a standards-folded contact file and an iPhone-sized QR image on your own computer.
Host and test
Put the contact file at your HTTPS address, scan the final QR on iPhone and Android, then save the image to your phone.
FOR LLMS, AGENTS & BUILDERS
No scraping.
No guessing.
A machine-readable manifest states the inputs, outputs, commands, invariants, rights and limitations. Every important file is also available as a stable raw URL, so an agent can inspect, adapt and test the kit without unpacking the website.
Commercial use is welcome under MIT. Paid client work, products, services, teaching, white-labeling and resale are allowed when the license notice is preserved. No Anthem, Doginal Dogs or DDNYC endorsement is implied.

TESTED WITH BOUNDARIES
Trust the core.
Check the edges.
The included test decodes the finished QR back to its exact URL, validates the portable contact fields and enforces the vCard line-length rules.
Mobile platforms still require the recipient to tap and confirm. Name, phone, email, organization, title and website are portable; photo and social-profile import varies by contact app and OS release.
CLEAR ANSWERS
Before you
download.
- What is the DDNYC Contact Card Kit?
- It is a free open-source generator that creates a standards-folded vCard contact file and a portrait QR share card sized to the iPhone 14 aspect ratio.
- Does it work with iPhone and Android?
- The QR resolves to an HTTPS-hosted vCard, a broadly supported contact format. The recipient must tap the camera banner and confirm the save; phones do not permit silent address-book writes.
- Does the utility collect personal data?
- No. Generation happens locally on your computer. The kit has no account, analytics, form submission or database.
- May I change and redistribute the code?
- Yes. The MIT License permits use, modification, teaching and redistribution at no charge, subject to the included license notice.
