I used to think choosing a barcode was simply about generating a set of black lines.
While researching barcode systems for small businesses, I learned that choosing the right format matters more than the design itself.
Code 128 is usually suitable for internal inventory, while UPC and EAN are intended for retail distribution. QR codes solve a different problem—they’re better for sharing links and customer information.
The barcode is the easy part. Understanding where it will be scanned, what it needs to contain, and whether it requires registration is what makes the system work.
A small detail, but an important lesson for anyone setting up product or inventory tracking.
