If you have any queries about QR Codes, we have compiled QR Code FAQs to answer all your queries and showcase the potential of QR Codes so you can start using QR Codes like a pro.
QR Code usage globally has multiplied in folds ever since its inception. By research, an estimated 11 million households will scan a QR Code in 2020 in the USA alone.
A QR Code is a 2-D square-shaped black and white barcode that can be read by smartphones. QR Codes store information that can be used to make a call, send a message/email, open a website, or even redirect to a location.
A QR Code can store up to 4296 characters or 7089 digits in a single code making it viable to hold large amounts of content.

QR stands for Quick Response. QR Codes are capable of being scanned within a couple of seconds, and hence the name.
A QR Code works in a similar fashion to that of a barcode. It is a machine-scannable image that can be read by smartphones either via its native camera or third-party apps. Every QR Code contains small data packets in the form of dots that hold a certain piece of information.
When a smartphone is directed at a QR Code, it displays the user information that is easily understandable.
QR Codes can be generated online in a hasslefree and inexpensive method. Use a free QR Code generator like Beaconstac to create any kind of QR Codes.

The minimum size of a QR Code should be 2cm x 2cm. However, the size of the QR Code depends on the medium of the outlet chosen.
For best results use this formula,
Size of the QR Code = Distance between the QR Code and the scanner / 10
For instance, if a QR Code is 33 cm, it can be read from as far as 3m.
The size of the QR Code is determined by the size of its modules and the version of the QR Code. The module refers to the black and white dots that make the data pattern and the version to use depends on the data to be encoded.
There are two versions namely –
Yes, QR Codes can be customized to any desired color, pattern, and template depending on the requirement. However, remember that only dynamic QR Codes can be edited after creating it.
Static QR Codes can be customized but there is no opportunity to edit them after downloading them.
A QR Code can be customized with the following options –

To put it simply, static QR Codes are uneditable after creating them; dynamic QR Codes are editable. Not just that, dynamic QR Codes can be tracked, analyzed, set landing pages, and can be customized as and when required.
Here is a table to simplify the differences –
STATIC QR CODES | DYNAMIC QR CODES |
Once created, the destination URL cannot be changed | Have the flexibility to change the URL linked to it – even after printing and distributing |
Stores the data directly in the QR code graphic | Stores a short dynamic URL on the QR code graphic |
QR codes that store complex data look extremely dense | These QR codes are less dense and are more reliable to scan. |
One cannot track the performance of a static QR code | The performance of a dynamic QR code can be tracked |
Once QR Codes are created, only dynamic QR Codes can be edited. Static QR Codes cannot be edited once they are created.
There are several free QR Code generators in the market to create a free QR Code. Beaconstac’s free QR Code generator offers robust experience and multiple features to create the best quality free QR Code.
QR Codes are free up to a certain extent. If choosing a static QR Code, they are free for unlimited use. If choosing a dynamic QR Code, they are free as long as the free trial period persists.

Yes, a damaged QR Code can still work. However, there is only up to a certain level that a QR Code reader can read the code correctly. Although today’s smartphones are equipped with the best technology, a 90% damaged QR Code is still not readable.
Always make sure that the QR Code is between levels M and H, and never H.
There are four main elements in a QR Code –
This indicates the direction in which the QR Code is printed. This insinuates that even if your camera is tilted at an angle, it will still scan the QR Code.
This basically helps a QR Code with its alignment to be able to be scanned without any errors.
This basically helps the QR Code scanner to gauge the size of the data matrix in the QR Code.
This is a vital part of a QR Code. A QR Code’s quiet zone helps differentiate the QR Code scanner from its surroundings.
QR Codes can be made more beautiful by customizing the QR Code accordingly. Change the color of the data pattern, add a frame, CTA, logo or a background image and change the modules accordingly to make the QR Codes more beautiful.
Avoid the following protocols in order to deem it as unscannable –

Dynamic QR Codes cannot be differentiated from static QR Codes, in terms of looks. However, the functionality differs drastically.
For a dynamic QR Code to function as a dynamic QR Code, a short URL is assigned to the QR Code and separate landing pages are created based on the time, location, and device to be used.
These dynamic QR Codes redirect the user to different landing pages based on the protocol set by the user on the dashboard.
Static QR Codes are absolutely free of charge. Dynamic QR Codes are free until the free trial period is over and once it is over, they are chargeable.
At Beaconstac, dynamic QR Codes start from as low as $5.
In the case of dynamic QR Codes, there is no limited scan-life and they do not expire. However, static QR Codes do expire, thus making it non-functional. When a static QR Code expires, it won’t redirect the user to a landing webpage, negating the entire purpose of a QR Code.
Dynamic QR Codes also expire. However, they can be configured to point to another destination once the campaign is over. They are editable, retrievable, and can be used for multiple purposes with no expiration.
With static QR Codes, that is not the case.
The QR Codes were invented by the Japanese company Denso Waves in 1994 to track vehicles during manufacturing for a unit of Toyota automobiles. They were designed to permit high-speed component scanning.
Yes. Once the QR Codes are downloaded, they can be used for any purpose, including commercial use.
Using a dynamic QR Code will also be helpful in changing the data as and when required to suit the requirements of the company.
A QR Code vector is a type of QR Code that is used for high-quality print materials, tech uses, flyers, or large print materials such as billboards that can be scalable without losing its resolution.

Yes, absolutely. QR Codes are omnidirectional and can be scanned without any trouble from any angle.
This is because QR Codes are included with a position detection pattern which helps the QR Code reader to recognize the correct orientation of the code.
Each QR Code comes with three-position patterns (finder pattern) that are positioned at the three corners and one small square that is the alignment pattern. The alignment pattern helps QR Code readers to align and read the code without any difficulty.
QR Codes are standardized by Denso Wave to ensure that every QR Code created is interoperable. Below is a history of the standardization of QR Codes –
Even if two QR Code stores identical data, the pattern might or might not be different depending on the QR Code generator used.
The primary reason for the change is due to the internal expression of the QR Code (numeric code, alphanumeric code, and so on). If this expression varies, then the data pattern also varies.
A QR Code stores data by following four kinds of modes –
Yes, a QR Code can store an image or an image gallery. An image gallery QR Code allows users to open up an image gallery upon scanning the code. This type of QR Codes are lesser-known but are an extremely useful way to explain a product to enhance cross-selling.
