“Keep-it�, an “intelligent label with memory�, records any temperature fluctuations in the cold chain and indicates the remaining shelf life in the form of a bar.

the vehicle or container. Parallel to this, GPS reception is briefly activated in the mobile phone and the exact geographical position of the object is recorded. The mobile phone then transmits via the Internet all the characteristics of the NFC chip (chip number, date and time) as well as the position to the central computer which manages the vehicles and containers.

GeoFence monitoring improves protection against theft Modern electronic systems also make transfer or rental of objects easier because all customer data can be recorded easily and directly by smartphone. As is in the meantime customary upon the delivery of a package, the customer confirms the receipt or the correctness of the information in the signature field. This is simple, practical and saves the time-consuming task of filling in forms. Documenting and invoicing are possible in real time. If a person cannot or prefers not to use the convenient NFC function

they can also of course enter the data via the barcode or QR code or enter it manually. In any case, all the details of the registered objects are stored in the system. The location is displayed with the complete address (town, street, house number) and as a GPS position in OpenStreetMap in the web portal. This option makes it easy to use electronic log books, complete with all routes, times and work breaks. An important argument in favour of GPS track and trace is GeoFence sector monitoring. This significantly improves protection against theft. Users are alerted by email, SMS or a signal as soon as a monitored mobile object reaches or leaves a certain area, neighbourhood or address. To avoid unnecessary disturbances during authorized transport the alarm function can usually be adjusted via a time window. The term geofencing, a composite of the words geographic and fence, refers to the automatic triggering of an action (e.g. alarm) when a predetermined boundary is

exceeded on the earth’s surface or in the airspace.

prevents loss of valuable raw materials, whether fresh fish or frozen.

Depending on the application area various GPS tracking modules can be used, for example self-sufficient mobile systems, some of which have extremely long battery life times of up to 10 years, or stationary installations that are permanently installed. They are usually very robust constructions in order to withstand the harsh conditions that can prevail on board a ship, for example, during container transport. Many have integrated acceleration and vibration sensors which automatically register and report any motion. Depending on the technical equipment and programming the modules report their positions several times a day at fixed times or in real time.

In this area, too, track and trace systems have quite a lot to offer. With the help of high-precision, robust and hygienic measuring instruments it is possible to monitor compliance with the required temperature limit values according to HACCP specifications throughout the entire process from the raw material to the finished product. As we all know, it is not sufficient to check and confirm the correct temperature of the delivery only in spot checks during goods receipt. Only permanent monitoring of temperature throughout the entire chain can provide the security that is required in this sector. The range of manual and automatic temperature measurement systems within the food industry is overwhelming. There are precise measuring devices and full-service offers, numerous individual services from repairs to rental equipment and calibration, as well as, of course, professional consulting.

Data loggers provide information on adherence to the cold chain Although barcodes, 2D data matrix, RFID and GPS offer fascinating possibilities they do not cover all the requirements of traceability systems. The seafood trade is a permanent challenge, not only when it comes to transporting freshly caught, quickly perishable products. The supply volumes sometimes fluctuate from one day to the next which can have a serious impact on transport and logistics service providers. They must always have sufficient transport capacities available even if the weather or the season prevents successful fishing. And this necessitates reliable risk and security management systems that enable them to identify, assess and eliminate disruptions in the supply chain in order to limit financial losses in this tough business. A central aspect of reliability within the supply chain is the perfect functioning of cold chains which

Infrared thermometers are available for manual sampling, for example. These measure the surface temperature of a product without contact in just seconds. Anyone interested in core temperatures is more likely to use probe thermometers. Good measuring technology delivers reliable results without requiring a lot of work. Data monitoring systems and data loggers that measure automatically, document temperature profiles and generate alarms in case of limit violations are used for continuous measurement of temperature and humidity values. These systems should be approved in accordance with EN 12830. They are indispensable if one wants to be certain that the required temperatures have been maintained during road, air, sea or rail transport. mk
