Are QR code users really limited to just looking things up?

Mostly, but not entirely. QR code access is read-only by design — scanning a poster can't edit or delete anything in your SDS library. That said, several optional toggles on the QR user's settings 123 let QR users help build the library out, or interact with printed labels, if you want them to:

• Allow QR users to add Barcodes to SDS in library 1 — lets someone on the floor scan a barcode and link it to the right SDS on the spot, instead of that always falling to an admin
• Allow SDS Request creation 2 — lets a QR user flag a product that's missing an SDS, so it shows up in your SDS Requests queue
• Allow QR users to print labels 3 — lets someone who only has read-only QR access print a secondary-container label directly, instead of needing an admin to generate it for them

• 1 Allow QR users to add barcodes
• 2 Allow SDS Request creation
• 3 Allow QR users to print labels

Note this toggle is about building your library — letting someone on the floor link a barcode to a product record — not about looking up an SDS by scanning a container's barcode. For scanning something on the container itself to open one specific SDS directly, see how do I create a product label with a QR code on it? below.

Two more settings on the same panel worth knowing about: Show amount to users who scan a container QR code but cannot change it displays a chemical's currently-tracked usage amount to a QR user as read-only information (they can see it, not edit it) when they scan a container-level code; and QR user access to label Content Display & Expiration Date is a gear icon opening a per-field control over what a QR user can do when printing a label — for each field (company logo, PPE symbols, icon captions, NFPA, HMIS, SDS QR on label, ingredients on label, custom information message), you choose "Show/hide only" or "Editable," so you can decide field-by-field whether a QR user can just toggle a field's visibility on the printed label or actually change its value (for example, filling in an expiration date).

The gear icon on Allow SDS Request creation also reveals something the toggle-only view doesn't: these settings can be scoped per QR poster/location rather than being strictly all-or-nothing. Opening it shows an Enabled/Disabled list of your QR posters, with a "+" to move one across — so, for example, you could let the poster at one location's employees request a missing SDS while leaving that switched off for another location's poster.
