# QR codes for inventory management

> QR codes beat 1D barcodes for inventory where phones are the scanners and labels are small: a 2 cm QR holds a full item URL that any phone camera reads, while barcodes need width and dedicated hardware. Encode short IDs pointing at your inventory system, print thermal labels in bulk, and stocktake by scanning.

## QR or barcode: the actual trade-off

The [general comparison](/docs/basics/qr-code-vs-barcode) applies, but inventory sharpens
it to a table:

| | 1D barcode (Code 128) | QR code |
|---|---|---|
| Data in 2 cm of label | ~10 digits, tightly | A full URL or 50+ character ID |
| Scanner | Laser or imager hardware | **Any phone camera**, plus imagers |
| Damage tolerance | One scratch across the bars kills it | Up to 30% loss at [EC H](/docs/spec/error-correction-levels-explained) |
| Scan speed on fixed hardware | Excellent | Excellent on 2D imagers |
| Reads at odd angles | Poor | Good |
| Legacy WMS hardware support | Universal | Check, [older laser scanners cannot read QR](/docs/scanning/2d-imager-vs-laser-scanner) |

The deciding question is usually the scanner fleet. If your operation already runs
dedicated 2D imagers, either symbology works and you choose by data needs. If the
"scanner fleet" is whatever phones your staff carry (true for most small and mid-size
operations) QR wins outright, because the phone camera is the reader and there is no
hardware to buy. The one caution: warehouses with legacy *laser* scanners cannot read QR
at all, so audit the hardware before relabelling anything.

## What to encode

Encode an **identifier, not data**: a short URL or plain ID that your inventory system
resolves
```
inv.example.com/i/BIN-A12-04
```

Item details, quantities and locations live in the system, where they change hourly;
the label carries only the pointer, so it never goes stale. A URL payload means any
phone scan lands staff in the right record with zero app friction; open-source and
commercial inventory tools generally accept scanning a code into a lookup field either
way. Keep IDs short, short payloads mean low-version codes with big modules that scan
fast on shelf labels; a plain-text ID via the [text generator](/text-qr-code) also works
for camera-into-field workflows.

Label everything that has an identity: **bins and locations** (the backbone: receiving,
picking and counting all scan locations), **SKUs** at the shelf edge, and, only where
you track units individually, serialised items, which is
[its own discipline](/docs/ecommerce/qr-code-for-serialized-products). If the goods are
long-lived equipment rather than flowing stock, you want
[asset tagging](/docs/ecommerce/qr-code-asset-tagging) instead; the distinction matters
enough that it opens that page.

## Printing labels at scale

Bin and SKU labels are thermal-printer territory:

- Generate ID sets [in bulk](/bulk) from your locations export, or
  `POST /api/v1/qr/batch` for **up to 1,000 per request**.
- At **203 DPI keep modules ≥ 0.5 mm**: short IDs make this easy; the
  [thermal guide](/docs/print/thermal-printer-qr-codes) and
  [Zebra settings page](/docs/print/zebra-and-label-printer-qr-settings) have the
  hardware specifics, including native ZPL QR commands for Zebra fleets.
- **Direct thermal fades**: fine for carton labels that live weeks, wrong for
  location labels that live years; use thermal-transfer or laminated stock for
  the permanent backbone, per
  [direct thermal vs thermal transfer](/docs/print/direct-thermal-vs-thermal-transfer-for-qr).
- Test-scan a printed label from picking distance [before rolling out](/validate).

## The stocktake workflow

Where QR inventory pays off visibly: counting. Scan the location code, scan or count the
items, move on, each scan timestamped and attributed, no clipboards, no retyping. Two
people with phones can rolling-count a small warehouse continuously instead of shutting
down for an annual count, and discrepancies surface per location scan rather than per
year. The label system is what makes that possible; the codes are cheap, the discipline
of scanning every movement is the real cost.

## FAQ

### Are QR codes better than barcodes for inventory?
When phones are the scanners, yes: any camera reads a 2 cm QR carrying a full ID, with damage tolerance barcodes lack. Operations with legacy laser scanners must stay on 1D or upgrade to 2D imagers, so audit hardware first.

### What should an inventory QR label contain?
A short identifier or URL resolving to the record in your inventory system, never the data itself. Quantities and locations change constantly; the label should only be a stable pointer, so it never needs reprinting.

### How do I print QR labels for hundreds of bins?
Export location IDs, batch-generate codes, and print on thermal-transfer label stock, direct thermal fades within months. At 203 DPI keep modules at half a millimetre or larger, which short IDs make easy.

### Can I run a stocktake with phone-scanned QR codes?
Yes: scan the location label, count or scan items, and the system timestamps each entry. Rolling counts by staff with phones replace annual shutdown counts, provided every stock movement is scanned with the same discipline.
