The client suggested putting QR code that leads on his website (domain name is 10 symbols). I think there is no reason to do that as it is not that long and can be typed manually. Also, QR codes are used primarily for payment or to redirect on the page that has a really long address.

On top of that business card will be given to clients from Europe and The USA where as opposed to Asia QR codes are not as widely used.

When should I use QR code on the business card?

Is it a common practice to put QR codes on business cards in Europe and The USA?

Only time I've ever found QR codes to be useful is to link to something like a hosted video or topic for a short term run. A good example I've had with a QR code and business card is going to an expo and the company's video demo that was on display was also accessible on the business card but to the left was the company details and web URL then on the right it was the QR code linking to a hosted video promo on Vimeo.

So to answer QR codes on business cards can be used for marketing or a business campaign for short term. If you do plan to get QR codes printed on business cards make sure to get a sample first and test the QR code. Nothing worse than spending several thousand dollars on a marketing campaign to find out a sales rep didnt check the QR codes.

Personally, I think that the popularity of codes is not the most important argument in Europe.

I do not often see such business cards but if I have already seen QR codes on business cards, these were business cards of companies or people very closely connected with IT. I have the impression that they served more emphasis on the modernity of the solutions used than the actual use of codes. The practical use of codes is limited as many phones do not support natively code recognition.

In my opinion, the use of a QR code should be conditioned by the effect a business card has on a user (at least in Eastern Europe). Of course, this does not apply to cases of long internet addresses, contests, special information for business card holders etc.

The article Will QR Codes Make a Comeback in 2019? says "Twice as many respondents in Europe and North America scanned a QR code in the past month compared to Q3 of 2015." But regardless of such optimistic forecasts, I would still go back to the basics.

I have added QR codes that point to websites, but not since 2012 and not on printed business cards. I probably would not do so unless needed as an accessibility features, such as low visibility. For example, is card's target audience folks in night clubs? See Using QR Codes to Make Presentation Materials More Accessible. Designing for a US audience, nowadays, I might add a QR code to trigger a highly valued experience: a special experience online or sequence of events on the local device. And I would make sure that a prompt or call to action encouraged the user to engage.

The Scan and Shake: A Lesson in Technology Adoption from China’s WeChat is a bit old, but has sound discussion points about adopting technology. They call out three conditions for adding an interaction element: Usefulness, Ease of use, and Discoverability. Given those condition, in discussing QR codes for website landing, I would discuss with the client:

• Usefulness: In the US, the user would need to know what feature the
  QR code provides before bothering. How can we incorporate the QR code
  to make it clear that it can be used instead of typing in the website
  address?


• Ease of use: Let's compare QR scanning & triggering URL to
  typing in the URL. Which experience is easier?


• Discoverability: A QR code is definitely discoverable on a business card,
  but see "Usefulness" -- the feature, itself, needs to be discoverable.
  Otherwise, it's just visual clutter.

I hope going through this sort of thought-experiment with your client results in either dropping the QR code feature, or transforming it into an exceptional experience for their users.
