Peer Reviewed & Fact Checked

1. Applications

* Book spine or inside-cover label linking to the catalogue record. * Shelf-end signs with a QR to the catalogue browse for that section. * Self-checkout machine supplement: scan book then member card. * Hold-pickup shelf: member scans a code to confirm collection.

2. Catalogue Link Format

Encode a stable permalink to the catalogue item. Many library catalogue systems support a direct URL per record. Avoid session-based or search-result URLs that expire.

3. Privacy

Member QR codes for borrowing must not contain personal data in plain text. Use a unique opaque token that the backend resolves to the member account.

4. Durability

Book labels face abrasion. Use a durable adhesive label with matte laminate, and place the label in a consistent position such as the lower inside cover.

Frequently Asked Questions

Can a patron scan a shelf QR without logging in?

Yes for public catalogue links. Reserve authentication for checkout or hold requests.

Should member QR codes contain their name or barcode?

Use an opaque token. Including a member number in plain text exposes personal data.
