How the Smart Tag™ works

  • Dynamic Barcode Technology: The Smart Tag™ features a dynamic barcode, where the black and white lines change based on temperature and time due to a custom-tuned mixture that reacts and expands across the barcode.
  • Error-free Data Digitization: Scanning the Smart Tag™ digitizes data, eliminating interpretation errors.
  • No Electronics Required: The Smart Tag™ operates without RFID or electronic components.
  • Integration with Existing Systems: It enhances and integrates easily with current systems for additional ROI.
  • Customizable Temperature and Time Thresholds: Tags are customizable for a range of temperatures (-4°F to 78°F) and time durations (15 minutes to 12 hours).
  • Universal Identifier Code Compatibility: The Smart Tag™ can be formatted to fit any barcode symbology used in business, like UPC, EAN, Code 128.
  • Branding Customization: Businesses can customize the top layer of a Smart Tag with their branding

Surpassing GPS and Expensive Data Loggers

Explore advanced solutions beyond GPS and Expensive Data Loggers - Discover how the Smart Tag™ outperforms traditional technologies

Traditional temperature monitoring devices present significant challenges: they are expensive, require costly maintenance, and involve complex reverse logistics with high loss rates. Frequent battery recharging and cybersecurity risks associated with USB ports add to the operational burden. The cumbersome data retrieval process, often resulting in an overload of difficult-to-interpret data in outdated PDF formats, leads to a poor end-user experience, highlighting the need for a more streamlined solution.
Color Change Indicators, while simple, suffer from significant drawbacks. The interpretation of results is subjective, often leading to a higher volume of customer service calls. Additionally, there's a notable lack of data capture and sharing with the shipper, creating a gap in the monitoring process.
Varcode's Smart Tag™ offers a cost-effective and reliable solution for temperature monitoring. It delivers clear, accurate temperature data and features customizable, cumulative temperature exposure windows. The tags are easily scannable using standard barcode scanners or mobile phones, effectively digitizing crucial data elements such as cumulative temperature exposure, location, time, and date. Additionally, all data captured by Smart Tag™ is accessible via a user-friendly, cloud-based platform, enhancing the efficiency and accessibility of temperature monitoring.
