FlexStr8 Launches NFC Temperature-Logging Label

Flexstr8 has launched a new disposable smart label designed to provide a complete temperature history of perishable goods. The Flexstr8 Temperature Logging SmartLabel is thin enough to be easily integrated into packaging, the company reports, making it suitable for monitoring products in the biopharmaceuticals, chemical and agricultural industries throughout the cold chain cycle.

The smart label has a battery lifespan of a year or more, depending on the logging rate, and contains 28 kilobytes of memory, allowing for 14,000 measurements. It features an internal accurate temperature sensor (default +/- 0.5 degrees Celsius) with a range of –20 degrees to +50 degrees Celsius (-4 degrees to +122 degrees Fahrenheit). The internal time reference offers accountability and traceability across the entire logistics chain of exposure, Flexstr8 says.

Communication with the tag, which supports the ISO 14443A standard, is accomplished via a Near Field Communication (NFC) RFID reader, such as those found in NFC-enabled Android-based smartphones. A free FlexStr8 SmartTemp app (available for android devices at Google Play) can be used to turn the logger on or off, and to set its log intervals (as short as every 5 seconds and as long as every 10 hours) and temperature limits. Logged data is graphically displayed, the firm reports, and can be dumped to device memory, uploaded to the cloud or e-mailed for further analysis. According to the company, an iOS version of the app is currently being designed around a custom inexpensive NFC reader attachment.

"Current temperature loggers are expensive, bulky, and have poor battery life. Furthermore, most data loggers are built under the assumption that they will be reused," said Eric Casavant, Flexstr8's head of product development, in a prepared statement. "However, many customers stated that they rarely get their data loggers back after shipment, prompting us to make an inexpensive disposable logger."

Available now, the label has a retail price of $15.99.
