Printing QR Bag Labels
Color-coded QR labels go on every bag before the core hits the return shelf. Techs scan them at the kiosk to confirm shipment — no spreadsheets, no lost bags.
◎Why bag labels matter
When cores sit on a shelf without labels, they get lost, swapped with wrong bins, or returned to the wrong vendor. A 30-second print step at point-of-pull eliminates that ambiguity. The QR code encodes the shop ID, core item ID, vendor, and due date — so kiosk scanning is instant and unambiguous.
◑Label color coding
Every label is printed in one of three colors based on how many days remain before the core deadline:
GREEN — Plenty of time
8 or more days until the return deadline. Ship when you have a batch ready.
AMBER — Due this week
4–7 days remaining. Schedule a run or flag for next-day pickup.
RED — Urgent
3 days or fewer. Expedite immediately or call the vendor to request an extension.
↑Step-by-step: printing labels
Open the Labels page
Navigate to App → Labels. You'll see all active shelf items that need labels. Items already labeled show a ✓ badge.
Select items to label
Check individual items or click "Select all" to grab every unlabeled core. Use the vendor filter to batch-print by supplier.
Click "Print Labels"
A print-ready PDF opens in a new tab. Each label is sized for a standard 4×2 in. adhesive label sheet (Avery 5163 or equivalent). You can also print smaller 2×1 in. labels if your printer supports it.
Print or save the PDF
Hit Print in your browser to send to your label printer. Or Save as PDF to print later. No special driver or app needed.
Attach to the bag
Fold the label around the top of the bag so the QR code is visible when the bag is on the shelf. Stack bags label-side-out for fastest scanning.
⬡What\'s encoded in the QR
The QR code is a compact JSON payload that CoreBack Kiosk Mode reads in one scan:
"shop_id": "shop_abc123",
"core_item_id": "item_xyz789",
"vendor": "NAPA",
"part_number": "AC-DELCO 25168491",
"due_date": "2024-05-12"
}
Because the payload contains the item ID, the kiosk can look up the full record instantly — even if the tech scanning doesn't know the part number.
◈Bulk printing tips
- →Print labels for an entire day's pulls in one shot — use the date filter on the Labels page to select all items invoiced today.
- →Need to reprint? Click the reprint icon next to any label. Lost labels auto-expire from the "unlabeled" queue after 24 hours of inactivity.
- →Multi-location shops: labels embed the shop_id, so cores returned to the wrong location are caught during kiosk scan.
- →No label printer? Print on plain paper and fold it inside a clear packing slip pouch on the bag. The QR still scans reliably.
