The range of applications for transponders in industry is so wide and varied that an exhaustive description would require several large books.
However, in principle four large groupings can be established for the industrial deployment of transponders:
Legal usage

A typical example of this is the vehicle immobilizer that prevents a car being driven away. All new cars now carry this technology in order to reduce car theft rates significantly. Previously, keys could simply be copied; today, the transponder in the key must be reproduced too. Simply smashing in a car window and hot-wiring the ignition just won't do the trick any more either. The transponder is checked at various points, and the vehicles electronics systems are then locked out if the correct response is not received.
Marketing and product tracking

There are projects for which a transponder is essential for marketing reasons, in particular when a product's transparency is to be depicted, along with how the path it followed was tracked. A company using transponders will be able to depict such matters significantly better and more comprehensibly than one using conventional methods. In short, the possibilities are virtually limitless.
Security measures

A typical example here would be the regulation of admission. For example, in the case of a research Laboratoryatory operating at varying levels of security clearance, access to various areas can be controlled by means of transponders, while the comings and goings of personnel accessing these areas can simultaneously be recorded.
Return of investment
Here the transponder is being used in a purely commercial sense, helping to break down overall costs into individual unit costs and amortisation over a given period of time. The food industry has for years wanted to introduce transponders into supermarkets, thus enabling wares to be scanned at the checkout; however, the costs of using transponders for small articles like chewing gum or baking powder are prohibitive in relation to the purchase price of these products.

The use of transponders is both possible and conceivable in all branches of industry - the sole deciding factor is what additional usages can be clearly shown to be economical. Naturally, amortisation can also take place Internally by means of rationalisation measures in respect of personnel costs or running costs.
The use of transponders is generally a complex combination of different forms of specialist expertise. In this respect the physical possibilities of various transponders, the use of the reading technology - mobile or stationary - appropriate for the respective application, data capture and data transfer to the master computer, are all key factors. Again and again we see that following the implementation of the measures decided on, additional and entirely unexpected rationalisation effects become apparent that were not originally envisaged during the planning stage.
