Next to each item there is a QR Code made on the website oqrcode.com showing its use. If you are reading this article on your cell phone and cannot scan, just below the image you have the link or demonstration text of what you would display on your screen if you scanned.

1. As labels

You probably already know that the classic barcode can be used to read labels and display their price, or the name of the product, right? But did you know that the QR Code can also do this, but in a more advanced and complete way?
You can register tags with QR Codes that say the name of the product, its price, supplier, manufacturer, category, weight and even image!

2. Connect on Wi-Fi

To create your Wi-Fi connection QR Code, access: oqrcode.com, select the Wi-Fi option and enter: your network name, type of security (usually WPA) and password. Ready!

3. Download files

You can direct your QR Code to a file download URL.
One day I went to a new restaurant to buy food, and after the purchase, the owner of the establishment showed me a QR Code that was on the counter of the store, which when scanning was downloaded the application of the restaurant on my cell phone.
This is a quick alternative for customers, because if the owner of the restaurant simply told me “download our app on PlayStore, it’s called XYZ” I would certainly agree with her, go away and would never have remembered to look for it on the PlayStore and install it, either by forgetting me or by pure lack of interest.

4. It is customizable

Did you know that a QR Code can lose up to 30% of its information and still work? This means that you can sacrifice some black dots from your QR Code to insert your logo or some flashy image right in the middle of it and still keep working!
By the way, little black dots? QR Code readers do not differentiate between colors, they just need to know the color of the pixels that represent the information, so you can change your QR Code to any color you want!
But be careful, although it is highly customizable, it is not recommended that you do it, as it can make it difficult to read your QR Code and even confuse people about what it is about.
