2. What does QR stand for?

QR stands for Quick Response. QR Codes are capable of being scanned within a couple of seconds, and hence the name.

3. How does a QR Code work?

50+ FAQs on QR Codes and QR Code Generator (2)

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.

4. How do I generate a QR Code?

QR Codes can be generated online in a hassle-free and inexpensive method. Use a QR Code generator like Beaconstac to create any kind of QR Codes.

Watch how to generate a QR Code –

5. What is the size of a QR Code?

The minimum size of a QR Code should be 2 cm x 2 cm. 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 3 m.

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 –

  1. Version 1 – This type of QR Code has 21 modules on its sides. For one version larger QR Code, the number of modules on the side increases by 4, and the largest version is 40.
  2. Version 2 – This type of QR Code has 25 modules on its sides. If the size of the module is 0.5 mm, the size of this QR Code will be 12.5 mm x 12.5 mm (although a white space of 4 modules must be placed around the code to use it).

39. Can a QR Code have different shapes?

Absolutely! You can create square/round-shaped QR Codes as per your liking. You can get even more creative by using different shapes for eye-balls, eye-frames, patterns, etc.

However, be mindful of the over customization of the QR Code and test the code for its scannability before deploying it.

40. Why do QR Codes have 3 squares?

QR Codes have 3 big squares at 3 corners (bottom left, top left, and top right) that contain the finder pattern and a smaller square towards the bottom right corner that contains the alignment pattern.

The 3 big squares allow the QR Code to be detected and interpreted by a QR Code reader. Whereas, the smaller square helps align the QR Code and ensures it is read even if the scanning angle is skewed.

41. Can QR Codes be copied?

No! No one can copy or hack into your QR Code unless they have access to your QR Code generator’s dashboard.

Even if someone tries to copy your QR Code and deploy it for their own use, they will eventually drive traffic to your destination URL configured in that QR Code.

42. Which QR Code is more complicated – Static QR Code or Dynamic QR Code?

50+ FAQs on QR Codes and QR Code Generator (11)

Static QR Codes are more complicated since they have dense data patterns, can be complex to scan, and have a longer URL as compared to dynamic QR Codes.

43. Can QR Codes be photocopied?

Yes, they can. All you need to do is ensure that the QR Code’s photocopy is good quality and not pixelated or smudged. This will make sure the QR Code is still scannable.

44. How long does a QR Code last?

Static QR Codes last as long as their destination URL is functional. Once this URL doesn’t work anymore, the static QR Code expires and doesn’t direct to any destination upon scanning.
