Recent developments in the realm of international trade have increased the need
for heightened security to prevent multi-frontal attacks. The dual missions of protecting
national security and collecting duties and taxes drive governments’ interest
in maintaining the integrity of the supply chain. The interest of private companies
in just-in-time, reliable delivery, cost-effective logistics, and maintaining the
integrity of goods leads to the development of many tracking systems.
Supply chain vulnerability is often overlooked as the movement of goods from the
manufacturer to the port or border crossing, or from the port to the distribution
center. Tracking represents an additional layer of security to ensure goods reach
their destination in the same condition as they began their journey, though other
layers must be put in place to achieve a more comprehensive level of safety for
vehicle and cargo transit.
Lost or resting cargo containers and vehicles represent the point in the supply
chain at which goods and conveyances are most vulnerable. Some studies have indicated
that 70 percent of senior executives are not satisfied with their ability to track
their moving assets to ensure integrity and safety. Tracking cargo and vehicles
allows for advanced processing of information by border and intelligence agencies
and assists in defeating the vulnerabilities associated with inland drayage, the
most vulnerable aspect of the supply chain. To adequately provide security, the
cargo and vehicle must be able to be tracked independently, but the tracking mechanism
needs the capability to associate the two data points.
Reltronics Technologies is a leader in developing, deploying and supporting novel
technologies for tracking assets, fleet, and various types of resources, had developed
most innovative way of tracking cargo and shipment using integrated technologies
like GPS, GPRS, RFID and Sensors. Reltronics Technologies utilizes complete advantage
provided by ReALTrack Framework for application development and support of Cargo
and Shipment Tracking System (ReALTrack – CST), which in-turn help the organizations
to utilize their current eco system without much change, in-order to provide better
Return On Investment (ROI) in shorter period of time.

RFID Technology in Cargo and Shipment Tracking
Radio frequency identification devices (RFID) are low-cost tags that assist in the
tracking of goods and vehicles. These devices are placed on individual items and
can either be active, i.e., constantly emitting a radio frequency signal; or passive,
i.e., only emitting a signal when queried by an outside source.
In order to track goods, readers (either hand-held or fixed) need to be installed
to track and record the numbers from the RFID devices affixed to each product or
container. Installation of these readers, however, adds additional costs which would
be assumed by the shipper or passed along to the consumer/end user.
RFID tags are limited in the number that can be screened by each reader at one time.
For large numbers of loose goods, individually tagging each good is not an efficient
use of resources. Tagging the unit containing these loose goods is a more practical
solution. RFID tags may not be practical for all applications, including tracking
liquids and items wrapped in metal or foil, as these environments can create interference.
The RFID tags only serve as a tracking Cargo and vehicle tracking is the ability
to trace goods, their containers, and their conveyances from the point of origin
to their destination. Tracking is increasingly associated with information transfer
using smarter tools such as radio frequency identification devices and global positioning
The RFID tags only serve as a tracking mechanism; they do not possess any effective
security applications. To work properly, specific frequencies will need to be designated
for RFID use only. Government assistance and cooperation is needed in order to prevent
interference with other existing devices and applications.
While RFID development is progressing rapidly, three issues could limit its spread
in the near future. First, there is an ongoing intellectual property dispute regarding
parts of the specifications related to commercializing the electronic product code
(EPC) technology. Second, EPCGlobal, the nonprofit organization charged with commercializing
the EPC technology, and the International Standardization Organization (ISO) differ
on the specification dealing with the numbering systems to which RFID tags relate.
Finally, many of the products being sold are not fully upgradeable to the next generation
of RFID technology that will be released shortly.
Authentication/Legitimization of Customs Procedures Tracking can help verify the
identity and contents of a vehicle or cargo container, and its use—coupled
with risk management techniques—make some of the current customs procedures
redundant. Elimination of those redundant procedures would expedite the customs
examination process and increase the assurance that the vehicle or cargo container
is safe and originates from an authorized or legitimate shipper.
RFID uses radio waves to automatically identify an object, often by storing a serial
number (and any additional information up to 2 MB) on an antenna. A receiver emits
a short-range alert when the integrity of the bulk has been compromised. Some RFID
tags also monitor environmental conditions.
Tracking automates the customs clearance system, thus minimizing the opportunity
for corruption through bribery of customs personnel. Barcode scanning simplifies
the tracking process by identifying the cargo and conveyance through an individual
code and a fixed reader and transmitting that information to a central point.
Benefits of Cargo and Vehicle Tracking Satellite Systems and GPS & GPRS
Global Positioning System (GPS) tracking utilizes satellites to monitor fleets of
vehicles or cargo containers, thereby ensuring there are no unplanned stops and
that a pre-planned route is followed. Geostationary Earth Orbit (GEO) satellite
systems use satellites that orbit the earth in order to continuously monitor a particular
These satellite mapping areas can be as large as North America or Australia, yet
can identify individual containers and vehicles. Networks of multiple satellites
that sweep the globe and monitor activity all over the world comprise Low Earth
Orbit (LEO) systems. This category includes voice-capable “big LEO’s”
and lower cost, data-only systems dubbed “little LEO’s.” Satellite
systems are only viable options for tracking when the transmitter located on the
vehicle or cargo has a direct line of sight to the satellite. They are consequently
impractical when utilized on double-stacked railcars, in the holds of vessels, and
in the stacks at container yards.
GPRS is utilized to send the information to and fro from a GPS enable device in
the remote areas. GPRS also helpful in integrating and sending information on additional
units like sensors and other functionalities based on the requirements.
