The purpose of the present invention is to provide a system which, in a product delivery procedure, monitors and manages, more simply and reliably, a deviation from a managed temperature during shipment. To solve the problem, provided is a logistics system, comprising: an information reading and transmitting device which reads an information code which is provided on a product and transmits data which is included in the information code; a server which accumulates, via a communications network, the data which is transmitted from the information reading and transmitting device; and a terminal device which refers to the data which is accumulated in the server via the communications network. The information code is formed from a pattern which changes with an occurrence of a deviation from a specified temperature. The system employs the information code.

Logistics system

The purpose of the present invention is to provide a temperature traceable indicator capable not only of displaying temperature history, but also adding other additional information. To that end, a temperature traceable indicator according to the present invention is provided with a base material and a temperature indicating laminate disposed on the base material, and is characterized in that the temperature indicating laminate is provided with a coloring layer including a color former, a color developing layer including a color developer for inducing the coloration of the color former, and a barrier layer disposed between the coloring layer and color developing layer, and the barrier layer includes a barrier agent that is immiscible with the color developer, is frozen at a first temperature, and melts beyond a second temperature so as to allow the color developer to become diffused in the coloring layer so that color is produced.
