Everything you need to know about the QR code What is it, how to create it, read it, and use it?
Surely you have used a QR code on some occasion. Aren't they very easy to use? This way of storing and transmitting information became famous in recent years and has become increasingly popular.
Despite this, and although they are already part of your daily life, do you really know what a QR code is and what it is for? Do you know what you need to read or scan them? And to create them? Well, in this post I will talk about it. I will also tell you about the tools you need to use them. So let's get started.
What is a QR code?
A QR code is an improvement of the classic barcode in which information is stored and whose capacity depends on whether letters and numbers (alphanumeric) or only numbers are used. The acronym QR stands for Quick Response a rapid response code.
These are small squares made up of black and white dots and lines that form different patterns. It is in these sections where the information is located, which can be extracted using a specialized scanner.
To preserve the readability of the QR code, its creators can print different levels of data correction, so that the scanner can read it even if it looks dark or is partially damaged. To do this, the information is repeated in several sections of the code so that the reader can find it when there are problems.
Most usually add a box in 3 of the corners of the QR, the idea is to make it easier for the scanner to read, being these reference points that allow you to more quickly identify the information within the complete box. All in all, this is just a help for the QR reader app as it can also do it without the boxes.
That is why, in terms of design, they can be found in different ways. In fact, there are those who add an outer line to them as if it were a frame. But regardless of their design, QR codes only fall into 2 types.
Types of QR codes
Static QR Codes
These always keep the same information, they cannot be reissued later. They are the most used.
Dynamic QR codes
In this case, they are created with the functionality of being able to modify the information. They are useful for cases in which the data has to be updated periodically and thus, not having to modify the code.
What is a QR code for?
QR codes have many uses and more continue to appear as technologies improve. Even so, these are some of its best-known features:
1. Take to a web page
This is the most common use of QR.
Here the address of a website or one of its pages is added and when the user scans them, he is taken to the site. This saves time and avoids transcription errors on the part of the user.
In addition, it takes advantage of e-mail, since with the latter you have to request the person's email to send them the link. While with the code you do not have to provide any personal data.
For example, restaurants use them a lot so that diners leave their assessment and a review on their website about their experience. It is a very effective way to gain online reputation.
It is also frequently used for letters.
2. To give personal data
Sending a vCard has never been so easy, because with the QR a person can add their contact information (phone number, email, name, etc.), the other person only has to scan it and they will already have the data saved in their device.
This modality is very practical for executives and businessmen, who want to disclose their personal data, but without the fear of it falling into the wrong hands. So they print their codes on business cards.
3. App Links
As with web pages, links to apps can also be embedded in these codes to take the user directly to the download platform, be it Play Store, Apps Store or any other.
Companies that want to provide a more personalized and mobile service to their audience are using QR codes to take their customers to the apps they have developed for that purpose.
4. Connect to a Wi-Fi network
Wireless networks are often protected to ensure stability and privacy. In order not to have to add the data manually to each new device that wants to connect, QR codes are created with the name of the network and the password.
This is a very good option for hotels and airports, where people who have already purchased can benefit from free internet connection immediately by simply scanning the code.
5. Go to social media profiles
Getting followers is not an easy task, especially if your lead has to search for you manually.
Therefore, it is best to have a QR that leads directly to your social network account. Of course, your user has to use the same platform, otherwise they will not be able to interact with your account.
Influencers use QR codes a lot for special events, as well as for commercial promotions, almost like a vCard.
6. Download files
This is another of the common uses and it is being used more and more. Creators attach a file, it can be an image, a song or a .pdf, .xls, .doc (.docx) document or just plain text.
They can be found mostly on subscription web pages where special information is given to premium users. Although they can also be used for free downloads.
7. QR codes to create an event in the calendar
Getting your audience to remember a special date can be difficult, so a QR that takes the user to your calendar app and automatically adds the information is very handy.
These are especially useful for sweepstakes campaigns and special events where the next one is invited.
8. Find a location on Google Maps
Local searches are quite common, especially to find service providers and businesses. With Google My Business these companies can add their location data and a description with images of what they offer to the public.
Well, with the QR codes, they can add their My Business data so that users can scan them and see where they are located. This is very handy for billboards, totem poles, and other print advertisements.
9. Make payments in cryptocurrencies
Bitcoin is the most used cryptocurrency worldwide and more and more people use it in their daily transactions. To simplify payments, QR codes can now be created with the payment recipient's data so that the sender only has to scan and open the Wallet to pay.
Although it is more practical for companies, the truth is that many Bitcoin users use it normally, so they only have to show their code.
How to scan or read a QR code?
The process of scanning QR codes is very simple and we can summarize it in 3 simple steps. You only need a smart device and have a QR code reading app downloaded; then just do the following:
Step 1: Open the app
Depending on the operation of each application, you may have to choose the scanning option, although there are apps that open automatically in this function.
Step 2: point to the QR code
In this step, it is very important that you point your camera at a good angle, although there are codes that can be read quickly and latest generation devices that are very effective, it is essential that you focus well, otherwise it will not work.
Step 3: open the content
The reading app will tell you what type of content the QR code has, you must click on it to be able to execute the action for which it was created (go to a website, a social network, etc.).
Keep in mind that some apps have a code reading function that does not work with all the QR you find.
This is very common in business applications such as supermarkets. From their app they allow you to buy and scan ONLY their QR codes that are programmed for special offers and promotions of your business.
This means that you may need extra applications depending on the type of function that the QR has.
For example, if it is about reading an office document, you will need a special app.
How to make a QR code?
Nowadays it is not a mystery how to create a QR code. In fact, there are hundreds of alternatives (which I will mention later). But no matter which one you use, the process is always more or less the same:
1. Enter an appropriate QR code generation platform
Although it seems obvious, this step is very important because not all tools will allow you to create the same type of codes. So check if you can actually do it.
2. Customize the QR code
You have to choose the type of content that the QR will have, then modify its appearance (color and shape) and add your logo (if you have a company).
In some cases, you can define if you will use a static code or a dynamic one, think well before deciding, this way you will avoid
3. Download your code
You will be able to download your code after customization, keep in mind that not all platforms offer the same download formats. Although in most cases you will find vector and pixel formats.
4. Check
As you can see, it is really easy to make a QR code, but it is good that you keep in mind some tips like these:
Test your code before publishing it, as in some cases there may be bugs or errors in editing. Try various reading apps to be sure.
If you want to create a free QR code, check that the platform you use really works that way. Some allow you to create simple codes at no cost, while customizations are paid.
Although making static QR codes works perfectly, using dynamic ones offers more advantages because you can reuse them without having to generate new ones.
Post your code in a conspicuous place and where it is easy to scan.
