Many organizations are reluctant to implement indoor navigation because they fear high hardware infrastructure costs. Beacon networks, WLAN positioning or ultra-wideband systems can quickly eat up five to six figures — budgets that smaller institutions or non-profit organizations in particular do not have.
There is an elegant, cost-effective alternative that is often overlooked: QR code-based indoor navigation. This technology uses the smartphone, which every visitor already carries with them, and combines it with simple, printed QR codes. The result is a full-fledged navigation system without hardware investment.
The principle is extremely simple: QR codes are placed at strategic points in the building — at entrances, elevators, stairwells or crossroads. Visitors scan a code with their smartphone camera, and the navigation app automatically opens with the current position as the starting point.
From there, users can select their destination and receive turn-by-turn instructions, just like with outdoor GPS navigation. The decisive difference to autonomous positioning systems: Localization is carried out by scan, not by permanent positioning. This is not only cost-effective, but also privacy-friendly.
Modern platforms such as Accuras have developed QR code navigation far beyond simple routing. The codes are linked to so-called LinkHubs — interactive landing pages that display additional information, services, or contextual content when scanned. For example, a QR code in the conference room can not only provide navigation, but also the current occupancy plan, booking options or technical equipment details.
The most obvious advantage is the financial aspect. QR codes cost virtually nothing — they can be printed, laminated and glued onto normal paper. Even high-quality, designed variants remain in the single-digit euro range per piece. Compared to Bluetooth beacons of 20-50 euros or UWB anchors in the three-digit range, this is negligible.
In addition, there is no need to install and maintain electronic components. No batteries that need to be changed. No radio interference that needs to be fixed. No IT integration of complex beacon networks. Implementation can be done within a few days, not weeks or months.
Another advantage is flexibility when making changes. When room layouts change or departments move, all you need to do is print and place new QR codes. In the case of beacon systems, such changes mean recalibration, repositioning, or additional hardware purchase.
Data protection also benefits: QR code navigation does not require permanent tracking. The app only knows where a user is when they actively scan a code. This is an important aspect for privacy-sensitive environments such as hospitals or government agencies.
The success of QR code-based navigation depends largely on strategic placement. Codes should be positioned at all main entrances so that visitors can start as soon as they enter the building. Other important positions include elevators, stairwells, long corridors and crossroads.
The viewing height is crucial: Codes should be placed at a height of around 1.20 to 1.50 meters — easy to scan for most people, including wheelchair users. The size must be sufficient for simple scanning from a distance of approximately one meter, typically at least 10x10 centimeters.
Design and context also play a role. QR codes should be integrated into the building design, not look like subsequent plasters. A short text instruction such as “Scan for navigation” in multiple languages significantly increases the usage rate. Ambient light and contrast must be taken into account — surfaces that are too dark or reflective hinder scanning.
An often overlooked advantage of QR code navigation is the ability to gradually expand. Organizations can start with QR codes and later selectively add more precise technologies without having to replace the entire system.
Flexible platforms such as Accuras support the parallel use of various positioning technologies. In areas where maximum precision is required — such as in surgical areas for asset tracking — beacons or UWB can be added. In less critical areas, QR codes remain the cost-effective solution.
This hybrid approach makes it possible to use budget specifically where the added value is greatest, instead of installing expensive hardware across the board. Users don't notice anything about this variety of technologies in the background — navigation works seamlessly for them.
QR codes with LinkHub technology open up possibilities far beyond simple routing. In museums, codes on exhibits can provide additional information, audio guides, or videos. In hospitals, they can lead to online check-in forms, waiting time information, or patient education materials.
Personalized routes are possible at events and trade fairs: Visitors scan a code at the entrance and receive an individual tour based on their interests. Exhibitors can place codes at their stands that lead to product information, contact forms, or virtual demos.
In facility management, QR codes on equipment or rooms provide quick access to maintenance history, operating instructions or fault reports. Technicians can document problems directly on site, with automatic links to the precise location.
The technical requirements for QR code navigation are minimal. Users only need a smartphone with a camera — a requirement that virtually everyone meets. Modern smartphones recognize QR codes directly via the camera app, without additional software.
For organizations, this means no special apps that users have to install in advance. Navigation can be browser-based or seamlessly integrated into existing apps. White label options enable fully branded solutions that are tailored to the corporate identity.
Administration is carried out via central admin consoles, where QR codes can be generated, linked content edited and usage statistics can be analyzed. Changes are activated in real time without the need to exchange physical codes — only the linked digital content is updated.
QR code-based indoor navigation offers a pragmatic, cost-effective introduction to professional guidance systems. With minimal investment, organizations can offer their visitors modern navigation and at the same time lay the foundation for advanced smart building functions.
The combination of low costs, easy implementation, high flexibility and expandability makes QR codes the ideal solution for organizations that want to introduce indoor navigation without immediately committing to expensive hardware infrastructure. Success shows that sometimes the simplest solution is the best.
