How to Use QR Codes for Inventory Management (Free Method)
Most inventory scanning advice assumes you have $500 to spend on a dedicated scanner. You don't need one. Here's how small business makers use QR codes — plus NFC and Bluetooth alternatives — to track materials and products with nothing but a phone.
Most inventory scanning advice assumes you have $500 to spend on a dedicated barcode scanner. You don’t. QR codes are free to generate, work with any phone camera, and are printable on standard address labels you already have.
Makers have three practical options for scanning inventory without expensive hardware: QR codes, NFC tags, and cheap Bluetooth barcode scanners. Each works with nothing more than a phone you already own. Which one fits your workflow depends on how you work, not how big your budget is.
Here’s what actually works for small business makers tracking materials and products.

The problem with dedicated barcode scanners
Dedicated barcode scanners are designed for warehouse environments: high-volume picking, team workflows, and integration with enterprise software. They cost $300–$700+ for a decent unit and require proprietary software that wasn’t built with makers in mind.
If you’re tracking jars of fragrance oil, skeins of yarn, or boxes of wick hardware, that kind of setup is overkill. You already have a better scanning device in your pocket.
QR codes took off during the pandemic as contactless menus and check-ins replaced printed materials — which means your customers, your suppliers, and almost certainly you already know how to scan one. That familiarity makes QR codes one of the lowest-friction ways to bring inventory management into a physical space.
Option 1 — QR codes (the sweet spot for most makers)
QR codes are the most practical starting point for maker inventory management. They’re free to generate, scannable with any phone camera, and printable on standard address labels.
How to create QR codes for free:
The simplest path: use a free QR code generator like QR Code Generator or QRCode Monkey. Enter a URL or text string, generate the code, print on address labels, and stick to your containers. For a basic system, that URL can be a row in a shared Google Sheet — scan to open the sheet, update the quantity, done.
It works, but it disconnects the scan from your actual stock data. You’re still manually updating a spreadsheet; the QR code just saves you typing the URL.
How it works with inventory software:
Craftybase automatically generates a QR code for every material and product in your inventory — no third-party sticker service needed. Scanning opens the actual stock record in your browser. Update the quantity, log usage, or record a new delivery directly from your phone.
That’s the difference: with a standalone QR generator, you scan to open a spreadsheet. With Craftybase, you scan to open a live inventory record tied to your costs, recipes, and order history.
Honest limitations to know:
- Requires a clear camera focus (damaged or crinkled labels can fail to scan)
- Updating stock requires an internet connection
- Won’t work with standard linear barcode readers
For most makers doing regular stock checks, these are minor inconveniences, not blockers.
Option 2 — NFC tags (worth knowing about)
NFC (Near Field Communication) tags are small physical chips you tap your phone against. No camera needed — just touch the chip with your phone.
Why makers are starting to use them:
NFC tags have been gaining traction in small-business communities as a faster alternative for high-repetition stock updates. Instead of pointing your camera at a label, you tap a chip stuck to the shelf bin or container. The tap triggers an action — typically opening a URL in your phone’s browser.
iOS NFC has improved significantly:
This is worth knowing if you shelved NFC years ago because of iPhone limitations. From iOS 14 onwards, iPhones can read NFC tags in the background — meaning you just hold your phone near the chip without opening any app first. Writing to NFC chips from iPhone still requires a dedicated app, but reading is now seamless. Android has supported background NFC reading since Android 4.4, so both platforms are now practical for a tap-based workflow.
Setup for a Craftybase workflow:
Craftybase doesn’t natively write NFC chips, but you can use them as a workaround. Each chip can be programmed with the direct URL of its Craftybase material or product record. Tapping the chip opens that record in your mobile browser, where you update stock as normal.
You’ll need an NFC writing app (free on both Android and iPhone) and NFC chips. Prices have dropped considerably — bulk orders of 100 chips typically come in at $0.15–$0.40 per chip, compared to $0.30–$1.00 a few years ago.
When NFC makes sense:
- You do frequent, repetitive stock updates throughout the day
- Your hands are often dirty or gloved (tap beats point-and-scan)
- You prefer a tactile workflow over a visual one
- You’re managing a storage area you pass through constantly (a tap-and-go at the shelf edge beats pulling out your phone camera every time)
Honest limitations:
- Chips need manual URL programming — one per material or product
- If the record URL ever changes, you’ll need to rewrite the chip
- Labels can delaminate in humid or chemical environments (wax workshops, soap studios)
For most makers just getting started with scanning, QR codes are the better first step. NFC is a workflow upgrade worth considering once you’re running a tight scanning routine.
Option 3 — Dedicated Bluetooth barcode scanners (when you actually need one)
If you’re processing high volumes — picking and packing dozens of orders daily, running a small team, or managing multiple storage locations — a Bluetooth barcode scanner starts to make sense.
The good news: you don’t need the $500 warehouse variety. Bluetooth scanners that pair with your phone start at $30–$80 and work with Craftybase’s mobile interface. They’re faster for rapid-fire scanning in a production environment, and your phone becomes the screen while the scanner does the input.
This is the right option if QR scanning starts to slow you down, not as a starting point.

How to set up QR code inventory tracking in Craftybase
Getting your QR scanning workflow running takes about 15 minutes.
Step 1: Add your materials and products in Craftybase. Each one automatically gets a unique QR code — no extra steps required.
Step 2: Print your labels. In Craftybase, navigate to a material or product record and print its QR code. Standard address labels (A4 or letter sheets) work fine.
Step 3: Stick the label on your storage container. Jars, bins, bags, shelves — wherever you physically store the item.
Step 4: Scan to update. Open your phone camera, point at the label, and tap the notification. The record opens in your browser. Update the quantity, log a usage event, or record a new delivery.
Once your most-used materials are labeled, stock checks become a matter of walking your shelves with your phone. No clipboard, no spreadsheet, no guessing. A regular stocktake becomes much less painful when you can scan each item in place rather than transcribing counts by hand.
Craftybase automatically generates a QR code for every material and product in your inventory. Print, stick, scan — no barcode scanner, no sticker service, no spreadsheet juggling.Try it free for 14 days.
Frequently Asked Questions
Can I use my phone camera to scan inventory without a special app?
Yes — any modern smartphone camera can read QR codes natively. For inventory tracking, you need software that generates and links QR codes to your stock records. Craftybase auto-generates a QR code for every material and product, so scanning opens the record directly in your browser and lets you update quantities on the spot — no barcode scanner hardware required.
What's the difference between QR codes and NFC tags for inventory?
QR codes are visual — you scan them with your phone camera. NFC tags are physical chips you tap your phone against. QR codes are cheaper to set up (free to generate, print on any label), while NFC tags offer faster tap-to-action in high-volume environments ($0.15–$0.40 per chip in bulk). For most makers tracking materials and products, QR codes are the practical starting point. NFC becomes worthwhile when you're doing dozens of stock updates daily and want to skip the camera step entirely.
Does Craftybase support NFC inventory scanning?
Craftybase doesn't natively write NFC chips, but you can use NFC as a workaround: program each chip with the URL of its Craftybase material or product record. Tapping the chip opens the record in your phone's browser, where you can update stock levels directly. It works, but requires manually writing URLs to each chip using a free NFC writing app. From iOS 14 onwards, iPhones can read NFC tags in the background — no app needed to tap and open the record.
Do I need a barcode scanner to use Craftybase?
No — Craftybase generates QR codes for all your materials and products, and you can scan them using your phone camera. If you prefer a handheld scanner, Craftybase also works with Bluetooth barcode scanners that pair with your phone. Dedicated hardware is optional, not required.
How much does it cost to set up QR code inventory tracking?
If you're using Craftybase, the QR codes are included — no separate generation service needed. You'll need labels to print them on (standard address labels work fine) and a printer. Total setup cost beyond your Craftybase subscription is typically under $20 for a roll of labels.
Can I use QR codes to track both raw materials and finished products?
Yes. Craftybase generates separate QR codes for materials and finished products. Scanning a material QR code opens its stock record so you can log usage or new stock. Scanning a product QR code opens the product record. This means you can track both sides of your inventory — what goes in and what goes out — with the same phone-scan workflow.
Once your materials are labeled and scanning is routine, you’ll have something more valuable than a neat shelf: you’ll know exactly what’s in stock at any given moment. That’s the first step toward understanding what your products actually cost to make — and calculating your COGS starts with knowing what raw materials you’ve used.
Knowing your current stock levels also helps you avoid the two most common inventory mistakes makers make: running out of a key material mid-order and stockouts that delay fulfilment. Scanning keeps you ahead of both.
If you’re still working out your tracking process before adding scanning, a free craft inventory spreadsheet can be a useful starting point while you get set up.
