A QR code (Quick Response code) is a two-dimensional barcode that stores data such as URLs, text, contact info, or Wi-Fi credentials. Smartphones can scan it instantly with the camera.

A barcode is a machine-readable representation of data using parallel lines of varying widths. Common types include Code 128, EAN-13, UPC-A, and Code 39, used for products, inventory, and logistics.

Static QR codes generated by our tool never expire. The encoded data is stored in the code itself and works forever, as long as the destination URL remains active.

Nine Barcode Formats for Retail and Logistics

From global retail standards to industrial logistics — our free barcode generator covers them all.

Four barcode format examples: EAN-13 retail standard, UPC-A North American retail, Code 128 logistics, and Code 39 government use — Each format is designed for a specific industry and scanner type.

EAN-13 & EAN-8

The global retail barcode standard outside North America. EAN-13 is mandatory for products sold in supermarkets across Europe, Asia, and beyond.

UPC-A & UPC-E

The North American equivalent of EAN. Required by Walmart, Target, and most US retailers. UPC-E is a compact version for small packages.

Code 128

The workhorse of logistics. Encodes letters, numbers, and symbols compactly — perfect for warehouse labels, shipping, and internal SKUs.

Code 39

An older standard still used by government, military, and automotive industries. Less compact than Code 128 but very widely supported.

ITF-14

Printed on shipping cartons to identify case quantities. Standard for moving boxes between warehouses and retail back-rooms.

MSI, Pharmacode, Codabar

Niche formats for inventory shelving, pharmaceutical packaging, libraries, and blood banks. We support every format you might need.

Real Use Cases Across Six Industries

A QR code is just a pattern of squares. What you do with it is what makes it worth printing.

Retail & E-commerce

Generate UPC and EAN barcodes for Shopify, Amazon, Walmart, and brick-and-mortar shelves. Pair with QR codes on packaging for warranty registration and product reviews.

Restaurants & Cafés

Marketing & Print

Branded QR codes on flyers, business cards, posters, and packaging. Track campaigns with unique URLs per channel and watch which creative drives scans.

Healthcare

Patient ID wristbands, medication tracking, lab specimen labeling, and equipment tags. Code 128 and Data Matrix are the standards in this space.

Logistics & Shipping

Pallet labels, asset tagging, and warehouse rack identification. Combine ITF-14 for cases with Code 128 for individual SKUs and you cover the whole pipeline.

QR Code vs Barcode: Which Should You Use?

They look different and they solve different problems. Here is the short version.

Feature	1D Barcode	2D QR Code
Designed for	Retail checkout, inventory	Marketing, customer interaction
Capacity	~20 digits	Up to 4,000 characters
Read by	Industrial laser scanners	Any smartphone camera
Read direction	Horizontal only	Any angle, omnidirectional
Best content	SKU numbers, GTINs	URLs, vCards, Wi-Fi, payments
Damage tolerance	Low	Up to 30% with high error correction

If you sell physical products, you almost certainly need both: a barcode on the back for checkout, and a QR code on the front or inside that drives a customer experience. Read the deep dive in our QR codes vs barcodes guide.

Tips for Printing QR Codes That Always Scan

A QR code that looks fine on your screen can fail completely on a printed flyer. Five rules that prevent every common failure.

1. Mind the Minimum Size

For close scans (table, business card) print at least 2 cm (0.8 in) wide. For posters, the rule is roughly 10% of the maximum viewing distance — a code seen from 2 m needs to be 20 cm wide.

2. Maintain a Quiet Zone

Leave at least 4 modules of empty space (about 10% of the QR width) on every side. Without it, scanners struggle to find the code's edges.

3. Use High Error Correction

If you embed a logo or print on a surface that may get scuffed, set error correction to H (30%). The code stays scannable even if a third of it is damaged.

4. Stick to High Contrast

Dark dots on a light background. Reversed colors (light dots, dark background) confuse many older scanners. If you need branded colors, keep the contrast above 4.5:1.

5. Always Download SVG for Print

SVG is vector — infinitely scalable, never blurry. PNG is fine for digital, but for any printed material above postcard size, use SVG.

6. Test Before You Print

Print one. Scan it on three phones (iPhone, Android, older device). Try in dim and bright light. Only then commit to the full print run.
