QR Codes Resources

We at Learnnovators have always been excited about Quick Response (QR) Codes. We have been doodling about leveraging the possibilities these quirky square codes offer while developing cost effective and powerful mobile performance support solutions.Today, when we are contemplating on a design for a mobile learning solution for one of our clients to help make their product unpacking and commissioning processes effortless, we set out on a journey to explore and learn more about this wonderful tool.Below are the questions we had in mind when we embarked on our journey:

QR codes resources

While the potential is great, in short a QR Code is a physical link that can be scanned by smartphones or tablets in mobile learning circumstances. The following list from listly user Marianna Talei offers a huge variety of QR resources, from QR code generators to attaching images and hosting QR code treasure hunts.

Inspired by an idea from Flapjack Education, students in Ms. Iles' room really kept learning in motion today. Using QR codes and jumbo plastic eggs, students moved about the classroom reviewing their addition, subtraction, and money counting skills using their own iPads.

Put your QR codes on the (google) map. Use the geographic QR code generator to create QR codes with your embedded co-ordinates. The geographic co-ordinates are stored and when scanned will redirect to a static mobile google map of your location.

On my Mac I use the iQR codes by Marek Hrušovský to generate QR Codes, I really like the batch creation option, check out my QR Code Bookshelf post and QR Code Bookshelf web site for an example of how I used the batch processing to make over 1000 custom QR codes in minutes.

An eventful QR code generator to help put your event on the calendar and in agenda's. This generator will allow you to create QR codes that when scanned can put your event on the calendar of the mobile device. Ideal for event driven marketing or to register an important date, anniversary or birthday.

Hey, ya'll! Rachel Lynette's Multiplication Jenga Labels have had me in love with the Jenga format for practicing math skills for a while now, so last week I combined that love with my love of QR codes in a self-checking Jenga game about fractions.

With the increasing use of smartphones, QR codes are becoming popular. Recently, WhatsApp launched its web version, which needs QR code scanning to access the web version of WhatsApp. So, many people now know what QR code is, but still more are unaware. It is very similar to a bar code we see in products, but it does not need a different reader. Our smartphone camera can easily read it with the help of a QR code scanner app. Due to fast readability, it is now widely accepted. And the use of QR codes is increasing. With the scan of a QR code, we can perform various tasks which would otherwise need a lot more effort. For example, scan a QR code and save the business card details in your smartphone. This is why people like to use QR code scanning for general tasks. But most users are not aware that QR codes can also be malicious. This is why scammers are now using malicious QR codes for tricking users.

This is a question about QR code people generally ask. QR code does not need any platform for redirection, but it has data within it. Once a QR code is generated, it can be used anytime, anywhere. The lifespan of the QR codes is unlimited, so you do not need to worry about lifespan. Generate and then use.

A QR code is the square matrix with small black square dots arrangement. Hacking a QR code means manipulation of the action without modifying the QR code. This is not possible. QR codes can be malicious and can trigger malicious action. But that QR code will not be the same as the legitimate QR code. Two QR codes with different actions will never be the same. You will certainly see different patterns in both QR codes. So, QR codes cannot be hacked. But It can be malicious and hackers can use a QR code for various malicious purposes. And there are various reports in which we have seen the malicious acts.

Phishing is the main security issue involved with QR codes. It is also described as QRishing by some security researchers. QR codes are generally scanned by a smartphone camera to visit a website. Now, many website ads put QR code along with a URL so users can quickly scan QR code to visit the website. This is where scammers try to trick users. As I already told you, QR codes cannot be hacked. So, hackers or scammers try to change the QR code added in the poster. They can also print the similar kind of fake posters and put in public places. Innocent customers will scan these fake QR codes to visit the websites but they will be redirected to phishing websites. Most people judge a website by its look and feel, and phishing pages look exactly similar to legitimate websites. In mobile devices, it is hard to check the full address in the browsers. Due to limited space, browsers do not show the full address in the URL field. And most people never try to check the full address. This makes users more vulnerable. When they use this phishing page to login, their passwords are compromised.

Although this phishing trick has limited scope, it is most effective. There are various case studies which clearly confirm that people generally trust QR codes and become the victim of QRishing at public places.

By using QR codes to point to this kind of malicious websites, we can easily trick users. Users cannot see the URL, so there is no point of doubt. In QR codes, there is no need to enter the URL manually, users only scan QR code. And they only know what you will write about the QR code.

Malicious QR codes have limited scope, but may be harmful. So, you need to be protective and always take care of your security while using QR codes. If you are going to use it from banners at public places, you need to be selective. There are few things which you can do to protect yourself from malicious QR codes and its attacks.

Although QR codes are not new, their use is still very limited. With the increasing use of smartphones, we have seen sudden a rise in the use of QR codes. Now various websites and apps let users use a QR code to login or complete other tasks. But there are still very few users who use QR codes. This is the reason why there is little reporting on malicious QR codes. Nobody wants to waste time on things which have low impact. But this will change very soon. With the launch of WhatsApp for web, now many users know how to use QR codes. So, we can expect another sudden rise in the use of QR codes. And when it is used by a greater number of users, attackers will surely find new ways to exploit its weaknesses.

As of now, QR code risks have limited scope, but when there are more users, there will surely become a bigger risk. In the near future, we will also see the use of QR codes for payments and money transfer. At that time, it will be very important to follow security rules. As of now, we only need to use a good and secure QR code scanner app and then relax. Having a good anti-virus and Internet security app is also recommended. This will warn if a website is a phishing website or trying to install a dangerous app in your smartphone.

My obsession with QR (quick response) codes began over a decade ago, when I was a 5th- and 6th-grade classroom teacher. I used QR codes on bulletin boards so that during Open House, families could scan them to view students' digital work. I also used QR codes for assignments so that students could easily check their answers. When I transitioned to higher education and became a professor in 2013, QR codes came right along with me, and I have used them in ever-expanding ways. With their simplicity and versatility, QR codes lend themselves to a wide variety of uses in the college/university classroom.

EDUCAUSE defines QR codes as "two-dimensional bar codes that can contain any alphanumeric text and often feature URLs that direct users to sites where they can learn about an object or place." QR codes have been used in various industries and settings, including museums (to provide visitors with additional information about the artwork on display) and airlines (to make the boarding process more efficient).1 There has also been a resurgence of the use of QR codes during the COVID-19 pandemic. For example, many restaurants have transitioned to using QR codes to give patrons access to menus in a way that minimizes contact with shared surfaces.

QR codes can be created using websites that generate QR codes or certain web browsers, like Google Chrome. The iPhone and iPad have a built-in app called Shortcuts that can also be used to create QR codes (see figure 1). With the Shortcuts app, you can create QR codes that link to websites, contact information, calendar events, and even wireless networks (to make it easier for others to join a network).2

To scan a QR code, you can use a mobile device with a camera, such as a cell phone or tablet. In fact, the cameras on most newer iPhones, iPads, and Android devices have built-in QR code reader functionality.3 If using an older device, you can download a third-party app to scan QR codes, such as QR Droid or QR Reader for iPhone.

QR codes are useful for many teaching and learning tasks in the higher education setting. Faculty and students can easily generate QR codes that link to a wide variety of online content including maps, charts, graphs, audio or video clips, photographs, quizzes, surveys, PDF documents, websites, and collaborative documents. The possibilities for how QR codes can be incorporated into courses of any discipline are endless. Below are just eight ideas.

One of the easiest ways to use QR codes is to provide students with quick and easy access to course materials. For example, QR codes in the syllabus can link to course readings or videos. Or QR codes on slides can quickly direct students to a website that they will be using in class. You can also create a QR code that points students to an online hyperdoc containing links to all of the resources that will be used that day. This becomes a "one-stop shop" for students during class and streamlines the navigation process.
