What is a QR code?

Generating QR codes is not difficult; you need to follow these simple steps to make it happen.

QR codes are also called Quick Response codes and have become very popular. They are small rectangular images containing machine-readable information used for data exchange. QR codes can create quick, easy-to-use links between different online resources. When someone scans a QR code with a QR code reader app, the app will typically open up a link in a new tab or window on their computer.

How does QR code work

QR codes are also called Quick Response codes and have become very popular. They are small rectangular images containing machine-readable information used for data exchange. QR codes can create quick, easy-to-use links between different online resources.

When someone scans a QR code with a QR code reader app, the app will typically open up a link in a new tab or window on their computer. QR codes are short, two-dimensional barcodes that can be scanned with a smartphone or other scanner app. They're commonly used to share links between different online resources quickly.

What Is a vCard QR Code?

A vCard QR code (also known as QR-code) is an image containing one or more URIs used as a barcode or matrix code for mobile phones with camera capability. A vCard is an electronic business card containing a person's personal information. NeXT Computer, Inc developed the standard.

The Two Types of QR Code

QR codes can be used for multiple purposes, but there are four widely accepted versions of QR codes. The version used determines how data can be stored and is called the "input mode." It can be either numeric, alphanumeric, binary, or kanji. The type of mode is communicated via the version information field in the QR code.

Numeric mode - This is for decimal digits 0 through 9. A numeric mode is the most effective storage mode, with up to 7,089 characters available.
Alphanumeric mode - This is for decimal digitals 0 through 9, plus uppercase letters A through Z, and symbols $, %, *, +, –, ., /, and: as well as a space. It allows up to 4,296 characters to be stored.
Byte mode- This is for characters from the ISO–8859–1 character set. It allows 2,953 characters to be stored.
Kanji mode - This is for double-byte characters from the Shift JIS character set and is used to encode characters in Japanese. This is the original model, first developed by Denso Wave. However, it has since become the least effective, with only 1,817 characters available for storage. A second kanji mode called Extended Channel Interpretation (ECI) mode can specify the kanji character set UTF–8. However, some newer QR code readers will not be able to read this character set.

There are two additional modes which are modifications of the other types:

Structured Append mode - This encodes data across multiple QR codes, allowing up to 16 QR codes to be read simultaneously.
FNC1 mode - This allows a QR code to function as a GS1 barcode.

A QR code is either a static or dynamic QR code. The difference has to do with the way they store information.

What Is a Static QR Code?

A static QR code is a fixed, uneditable QR code. The more information you store, the more extensive and more complex a static QR code is. With large or complicated sets of characters, a fixed QR code can look very busy and take slightly longer to scan.

But the biggest drawback to using a static QR code isn’t QR code size or speed. It’s editability. Once you learn how to make a QR code and create a static QR code, it can’t be edited. The information in the code cannot be changed until and unless you create a brand new QR code.

They’re best used for simple data and one-time use scenarios. Like ID numbers, product or serial numbers, or check-in information for hotels or events.

What Is a Dynamic QR Code?

A dynamic QR code is a QR code that can be edited after creation. As many times as you want. That means you can change the information encoded in a dynamic QR code without having to create and distribute new QR codes.

They do it by changing a short redirection URL to a QR code. Upon scanning, users are taken to the URL where they see the information. Because their data modules include only a single URL, dynamic QR codes are more straightforward and tend to scan and load quickly. They also track QR code usage—an indispensable quality for QR code marketing.

For most applications, dynamic QR codes are your best bet. They’re not more complicated to create than static QR codes, and they’re much more versatile. Indeed, any QR code that requires editing information (think of consistently changing coupons or digital menus) and tracking must use dynamic QR codes. Also, QR codes that need to scan and be tiny, like QR code nutritional information or food labels, should go dynamic.

Do QR codes collect my personal information and data?

QR code-generating software does not collect personally identifiable information.

The data it does collect – and which is visible to the code’s creators – includes location, the number of times the code has been scanned and at what times, plus the operating system of the device which scanned the code (i.e., iPhone or Android).

Can someone hack a QR code?

The QR codes themselves can’t be hacked – the security risks associated with QR CODE derive from the destination of QR codes rather than the codes themselves.

Hackers can create malicious QR codes which send users to fake websites that capture their data such as login credentials or even track their geolocation on their phones.

This is why mobile users should only scan codes from a trusted sender.

Are QR codes safe?

Attackers can embed malicious URLs containing custom malware into a QR code which could then exfiltrate data from a mobile device when scanned. It is also possible to embed a malicious URL into a QR code that directs to a phishing site, where unsuspecting users could disclose personal or financial information.

Because humans cannot read QR codes, it is easy for attackers to alter a QR code to point to an alternative resource without being detected. While many people know that QR codes can open a URL, they can be less aware of the other actions that QR codes can initiate on a user’s device. Aside from opening a website, these actions can include adding contacts or composing emails. This element of surprise can make QR code security threats especially problematic.

A typical attack involves placing malicious QR codes in public, sometimes covering up legitimate QR codes. Unsuspecting users who scan the code are taken to a malicious web page that could host an exploit kit, leading to device compromise or a spoofed login page to steal user credentials. Some websites do drive-by downloads, so visiting the site can initiate a malicious software download.

Mobile devices, in general, tend to be less secure than computers or laptops. Since QR codes are used on mobile devices, this increases the potential risks.

How to read a QR Code?

  • Install the scanner on your mobile phone from Play Store or Apple store 
  • Open the application and then point the camera on your phone to the QR Code.
  • The application recognizes that QR code and takes the appropriate action, usually opening a web page.

QR code with logo/image

This QR code standard includes an incredibly developed error correction technique (Reed-Solomon error correction). It is, therefore, possible to modify certain parts in QR codes. For instance, our generator can change the background and foreground-background color of a QR code, and it's also possible to insert a custom logo, e.g., within the center of the QR.

Embedding content with icons or logos can help users understand what they can expect when they scan the QR code before checking the code, even though the QR code's contents won't be displayed before taking the image.
