QR codes might seem like a modern innovation, but they have been around for over 25 years. Originally developed as an upgrade to barcodes, QR codes can hold far more information and can be scanned from any angle. Today, they are everywhere, from restaurant menus to product packaging, asset tags, and they provide a simple way to connect the physical world with digital applications.
Zest’s tag combines the versatility of QR codes with our Ultimate tags, creating a solution that is both smart and incredibly tough. Printed at 1200 DPI, undersurface with a velvet finish, and using UV-resistant inks, these ultra durable tags can withstand scratches, chemical cleaners, saltwater, extreme heat, and impact. Because the QR code is integrated into the tag itself, it remains scannable even in the harshest outdoor environments, making it perfect for EV charging stations and other high-traffic areas.
More Than Just a QR Code
Scanning a Zest Ultimate tag takes users straight to the Zest app install page, providing a seamless experience. But the possibilities with QR codes go far beyond linking to a URL. When printed on high-quality ultra durable tags, a QR code can store:
- Asset information such as charger IDs, serial numbers, and maintenance logs
- How-to guides, tutorials, or safety instructions
- Service history and inspection records
- Automated app triggers to streamline operations
Although the tag itself does not actively track location, it can work in tandem with apps that log GPS coordinates when scanned. For instance, scanning a QR code at a charging station could record its location, helping operators monitor usage, schedule maintenance, and optimise network performance.
Built to Last
Not all labels are built to last outdoors. Sun, rain, chemicals, and constant handling can make QR codes unreadable over time. Zest’s Ultimate tags are designed to be ultra-durable, maintaining scannability and clarity no matter the conditions. This longevity reduces replacements, lowers costs, and ensures your investment continues to perform over the long term.
Whether you are managing EV chargers, rental equipment, or other high-value assets, using Zest’s Ultimate tags with integrated QR codes is a simple yet powerful way to connect your physical assets with the digital world. With ultra durable tags like these, you get reliability, resilience, and smarter asset management in one solution.
