Business cards have been, for centuries, a symbol of professionalism.

However, in the digital age, where 81% of professionals search for information online before making a decision (HubSpot, 2023), the physical format is no longer enough.
[QR]This is where QR codes emerge as a bridge between the tangible and the digital. It’s not just a square of pixels: it’s a tool that can redirect to your portfolio, display a presentation video, or even schedule a meeting in your client’s calendar. In this article, we will explore not only the “how,” but also the “why” strategy behind its use, backed by data, real cases, and advanced techniques.
A QR code (Quick Response) is a two-dimensional barcode created in 1994 by the Japanese company Denso Wave to track automotive parts. Unlike linear barcodes, it stores information in two dimensions, allowing for up to 7,089 numeric characters or 4,296 alphanumeric characters.

Real example:
The consulting firm McKinsey & Company includes QR codes on its cards that redirect to exclusive reports on industry trends. This not only generates qualified leads but also positions its executives as experts.

[QR]At the SXSW 2024 event, Netflix distributed cards with QR codes that, when scanned, displayed exclusive trailers of their new series. Users who shared the content on social media participated in a draw for free subscriptions. Result: 15,000 scans in 3 days and a 22% increase in Twitter followers.
Deloitte includes QR codes on its consultants’ cards that redirect to micro-courses on digital transformation (e.g., “Blockchain in 5 Minutes”). This reinforces their positioning as leaders in innovation.
A QR code that leads to a 404 error can damage your credibility. Use tools like Bitly to update URLs without changing the code.
A study by NNGroup shows that CTAs increase conversion rates by 47%. Effective examples:
A QR code that directs to a page with 10 forms and 5 videos overwhelms the user. Best practice: One action per code.

In a market where 63% of professionals forget 90% of the cards they receive (Forbes, 2023), a QR code is not an option: it is a survival tool. By integrating it, you turn a piece of paper into a gateway to your personal or corporate brand.
