QR codes & quick actions

ScaleVault prints QR codes you can stick to enclosures and animal labels. Scan one with any phone camera and you're taken straight to a prefilled action form. No login required (by default — see QR auth).

Where to find them

• Per animal — animal detail page → QR tab. Each animal has codes for Feed and Handle.
• Per enclosure — enclosure detail page → QR tab. Each enclosure has codes for Feed enclosure, Clean, and Water check.
• QR cart — at /qr-cart. Add several animals or enclosures to a cart, then print a sheet of labels in one go.

How they work

Each QR encodes a URL like:

https://yourapp.example.com/quick/feed/<animalId>?accountId=<id>&sig=<hmac>

The sig is an HMAC of the action + animal id + account id, so the URL can't be tampered with — changing the animal id invalidates the signature and the page refuses to load.

This means you can hand a printed sheet to a contractor or feeder without giving them a login and they can only do exactly what you printed.

QR authentication

By default, scanning a QR works without logging in — that's the whole point. For higher-stakes actions you can require a login at the account level or override it for individual animals and enclosures.

Account-level defaults

Go to Account → QR & quick actions → toggle on the actions that should require auth across the whole account:

• ☐ Require login for Feed
• ☐ Require login for Handle
• ☐ Require login for Clean
• ☐ Require login for Water check
• ☐ Require login for Enclosure feed

Recommended setup for a multi-staff facility: leave Feed and Handle open, require login for Clean and Water check.

Per-animal / per-enclosure overrides

You can override the account default for any individual animal or enclosure. Open the animal or enclosure detail page and find the QR & share settings panel (visible to admins and owners).

• Use account default — inherits whatever the account-level setting says.
• Override: require login — this animal/enclosure always requires a login, regardless of the account default.
• Override: allow without login — this animal/enclosure is always open, even if the account default requires auth.

This is useful when most of your collection is staff-only but you want one enclosure's QR to be scannable by volunteers without an account.

Printing

The QR detail dialog shows the code at print size. Browser print (Ctrl/⌘ + P) → adjust margins → print to a label printer, or save as PDF and import into your label software.
