Interpretation:

Process chains among suppliers and final customers
The corporate strategy is the basis for successful business management and the starting point for creating all the business plans. Corporate strategy means the formulation of basic enterprise development processes. Enterprise strategy includes its strategic goals and strategic operations.
Thus, the corporate strategy is an open, active system that responds flexibly to new conditions in the company surroundings, both in the short and long term horizon. Therefore, conditions for enterprise stability, efficiency and prosperity are created. In the field of market economy, the corporate strategy is inn the interaction with the market and competition. We derive from the corporate strategy the concept of competitive products or services, etc., the selection of suitable production technologies as well as the enterprise logistics concept including communication systems.

Logistics provides and controls the movement of objects (e.g. products, pallets, orders, etc.) through partial process of the chain processes. Transformation of objects, i.e. machining, storage, handling, control, etc., takes place in individual processes. Among processes, the exchange of material (matter, substances) and information occurs. The task of logistics is to control the integrated material and information flows. The level of interactions among process chain elements affects the quality of logistics and the level of communication systems is therefore the main aim of logistics experts.

RFID – Hardware and Software integrated into material flows
Recently, many research and development studies and works have been carried out in the field of improving the properties and implementation of radio frequency identification. Especially, as far as the introduction of these executive elements into intralogistics is concerned.
 
RFID (Radio Frequency Identification) - of radio frequency identification, at the current stage of development, enables unambiguous contactless identification of almost any object using means of electromagnetic waves. RFID technology was developed in the mid-20th century for military purposes. Intense development, miniaturization and price reduction have led to the discovery of new options for the usage.
Establishing the RFID technology enables to optimize the value-creating processes. Already mentioned intensive development, resulting in increasingly smaller, advanced and cheaper components of RFID systems, has led to the increasingly widespread use of RFID in a wide range of fields - in trade, manufacturing, storage, transport, handling, etc. Transponder technology is a complete information management which replaces all the manual data processing.

Transponders are systems that enable to exchange the data via transmitting and receiving units. The transponder consists of a transponder antenna, which for obvious reasons is smaller than the antenna system of the communication unit, and a chip. The chip is used to store the data and performs the function of controller. Active transponders also have an energy source and can process and transmit the information. They also have greater communication reach. Their disadvantage is the larger dimensions and the necessity to replace the batteries. Passive transponders gain energy by induction through the antenna system of the communication unit and require no maintenance.
