DeltaTrak's cold chain solution includes the ThermoTrace TTI labels and the ThermoTrace TTI Alert Service. The solution provides immediate feedback messages to anyone who scans the TTI time temperature indicator label with an industrial barcode reader (WiFi/GSM/CDMA) or consumer based smartphone (iPhone and Android Windows CE). The application will display pre-defined messages on the screen of the reader or custom messages as defined by the service subscriber. TTI Alert Service customers can also receive email and text alerts.

Customers who subscribe to ThermoTrace TTI Alert Service can completely customize both the scanner feedback message and the email and text alerts. The temperature monitoring application will display a feedback message on the screen of the reader as defined by the service subscriber. As an example, the message displayed could say "good" or "fresh" indicating the product has not experienced any temperature abuse, or it might say "do not accept" if the product has experienced extreme exposure to abusive temperature.

Customized alert messages can be directed to up to five different people, as defined by the service subscriber, such as appropriate Quality Assurance or Food Safety personnel who could then take corrective action if necessary. The alert message is comprised of multiple components including the unique serial number found on each ThermoTrace TTI time temperature indicator label. The interactive DeltaTrak Scanner application allows users to scan or key in additional information which is then tied to that serial number and appears as part of the alert message. The user for instance could input a purchase order number, lot code, their product UPC code or an alpha-numeric message.

Visibility of product temperature abuse can be observed by anyone in the cold chain, from suppliers, processors and manufacturers down to the retailers. Because the labels can be applied at the carton level the ThermoTrace TTI Alert service fills an important traceability gap between the distribution center and the store. This temperature monitoring system can also be used to monitor the last mile when products are shipped directly to consumers.

The greatest value of the ThermoTrace TTI Service is its traceability features. Customized alerts are documented in text and email messages and tracked directly to your product by linking the ThermoTrace TTI label serial number to your product UPC code, order number, or alpha numeric message.
