Introduction to QR code and its use

[mstlucky0110]

Today, almost every person uses links to their pages, contacts, business cards, with information about their business. More often we see such a link tool as a QR code. Let's figure out what it is and how to make a QR code with a link through free services to transfer the user to your site or page.
qr code on the page
QR code is a black and white two-dimensional barcode that allows you to encrypt links to a website, mini-landings, social media and messenger profiles, or just text. It is read using a smartphone camera or special scanning applications.

How does 2D code work?
The tool was created to encrypt large amounts of information, compared to a regular barcode. QR can accommodate 4,000 symbols and small images up to 4 KB in JPEG, GIF, PNG format. Theoretically, with such characteristics, you can fit a whole book. Coding occurs in different types: digital (encryption of numbers), alphanumeric (text/numbers), byte (whole files), separate coding of hieroglyphs.

Generation is available using online services available upon qatar mobile number direct request for QR code creation. These are simple services that offer to select the type of data to encrypt - link, text, business card, link to the site. Paste the URL of the site page into the input field and click the code creation button. Different services will offer several design options (size, color, somewhere - creating a "label" image in the center of the code). Next to the generated code there will be a link to the image and HTML code for insertion into the main site code.
Dynamic QR code
Implies a transition to a page where the author can constantly make changes. A great example of such a page is mini-landings (read more here ). Using a dynamic QR code ensures that the user receives up-to-date information via the link. If you have distributed a dynamic code and then noticed some error on the site, or wanted to somehow change the information about your products or services, contact buttons in social networks and messengers, you will not have to re-generate a new QR - the transition via the already created code will take into account the changes made.
On some generator sites, you can enable the automatic link click function. When scanning, the user will immediately get to the site. Without this function, the encrypted URL of the page will be shown.
