Don’t mix it up, Qr Codes and Bar Codes aren’t the same. I’ll show you the difference below. This post here will show you how to.

When QR codes first came out, it seemed promising, but for a while It didn’t meet up its expectations. The birth of Smart phones made it more relevant.

Website links, ticket websites, contact info, coupon codes and a whole lot of other materials still use them actively.

On like Android devices, iOS 12 and above have the Bar Code/Qr code scanner embedded in their devices’ cameras.

No official confirmation for now, but I believe come September 2019, the iOS 13 will have the feature in it.

What Is Barcode

A barcode is a physical representation of machine-readable info about what it is attached to. You can simply call it a small box, mostly found on the box or front of a product.

It is made up of parallel black lines with different widths. A barcode may have information like product name, product’s manufacturer’s name, price, etc. The lines are data stored horizontally, so it is termed linear or 1D.

What Is A QR Code?

QR code which is an abbreviation of Quick Response Code. This is a type of Barcode, so yes! It contains readable information which could be understood by just machines.

Unlike your common Barcode, a QR code is two-dimensional, which means information is stored both vertically and horizontally. A QR code is a pretty big database.

What Are The Differences Between QR Codes And Barcodes

A QR code may be a type of Barcode, they may have the same mission, but there’s still a pretty big difference between both. Some difference is very obvious, others aren’t.

1. Appearance

It’s quite obvious, Barcode = A set of varying horizontal lines.


QR Code = Random black and white designs with three big square dots at the upper left, upper right and lower left.

2. Information Capacity

O yeah! The QR Code is an upgrade to Bar code, so yes it has more cool features. A QR code holds more information than a Bar code, it has the capacity to store a whole lot in a small space than a Bar Code. It’s a two-dimensional feature makes this possible.

3. Prone To Error Correction

The QR code is more flexible on like its predecessor, QR codes are getting a whole lot of popularity in society today, thanks to smartphones. A few altering of the QR codes pictures wouldn’t affect too much data, we can’t say the same about the Bar Code.
