Temperature Indicator Labels

Data loggers have been the foundation of cold chain logistics for years. However, data loggers replace one problem with another: they’ll provide lots of data, but it’s up to the shipper to make sense of it.  And they are expensive.

Varcode has responded with the Smart Tag™.  These innovative temperature indicator labels & barcodes provide dynamic temperature updates to your cold chain logistics professionals at any point during the journey, at a fraction of the cost of electronic data loggers.

Digitized Time Temperature Indicators

Varcode’s patented Smart Tag™ utilizes technology that causes the barcode to shift dynamically as the temperature changes within the shipping container. The labels provide cumulative temperature-time exposure at a variety of time intervals and can tell when the shipment dropped below an acceptable temperature range for a predetermined period of time. The result is a barcode that can tell a story every time it’s scanned.

  • The SmartTag™ can be applied to the product in-line or post-production.
  • Format the SmartTag™ in any industry barcode standard, including UPC, EAN, Code 128, and more.
  • Shipping pharmaceuticals or food? Varcode designed the SmartTag™ to aid with FDA compliance.

Varcode is dedicated to customizing your temperature monitoring system to your business needs. Our Smart Tag PLUS™ comes in a variety of standard time and temperature configurations based on industry needs ranging from -4°F (-20°C) to 104°F (40°C) with time parameters from 15 minutes to 24 hours or more.
