Somehow, the QR Code reminds me of an indecipherable jigsaw puzzle. The similarity is close because the QR (Quick Response) code is a black and white matrix that can only be read by special QR code readers.
Think of them as two-dimensional barcodes that are cuter than the vertical bars we’re used to with packaged goods and books. Not only does it look good, but a QR Code contains more information and is readable even when a code is obscured.
Originally a product of the car industry, QR codes can now be found everywhere; Even fashion accessories. Smartphones with QR code readers have made their use more common to exchange information. That’s why nowadays many web services have made it very easy to create your own QR code and use it for communication. Google Image Chart Editor is one of the free tools you can use. One of the most common uses is to encode website URLs and email addresses.
5 easy steps to create your own QR code
Here’s how you can quickly generate QR codes using the free Google Image Chart editor.
1. Start by selecting QR Code from the full gallery list. Click on the image of the QR Code to go to edit mode.
2. QR Codes use different character encodings as specified by different international (and Japanese) standards as shown in Options for QR Codes. The use of the QR Code determines the standards you should choose. For example, UTF-8 is a character set used in many software applications and operating systems. ISO-8859-1 is the default character set for most browsers.
Click one of the buttons to set the size. Size selection will again depend on the medium used. It should be optimal for scanning accuracy and scanning distance by QR Code reader.
3. Enter your text in the text box. Example: https://www.guidingtech.com
4. Other controls like Size, Fill, and Style go into the background design of the QR Code. For accuracy, a good contrast between the background and the color of the bar should be used. It’s best to keep the QR Code’s black and white color on a light background.
5. The right side of the editor gives you hyperlinks and embed links to paste into your blog, message board or email. You can also right-click on the created image file and save it on your desktop for later use in a Word document.
