The development by securing lines to the RFID technology the oldest way of securing goods is the simple link, include or chaining. Preferably wire ropes used here today. The electronic goods systems have prevailed over time however. Currently you can radiofrequenten (RF) electromagnetic (EM), and akustomagnetischen (AM) different systems. The various systems are characterized by your differing technological characteristics such as reliability, security, passage widths and detection rates. Usually, transmission-reception devices (antenna or gates), which stimulate the goods labels a certain frequency to vibrate is located in the output range.

RF this often 8.2 MHz is on most systems 58 kHz systems. The merchandise security tags at the moment distinguish between hard labels, self-adhesive labels and multi alarm labels. These differ E.g. pins or loops, their cost and security respectively in their method of attachment. Conventional hard labels and self-adhesive labels are Unfortunately easy to manipulate or remove (magnet, bend the labels, etc.). Here already the multi alarm labels or even 2 or 3 – alarm offer better protection labels, which have then, but also comparatively high acquisition costs. The term RFID (“radio frequency identification”) added a further component for securing goods.

This system offers the ability to recognize data, with the help of a reader and store. This allows the combination of anti-shoplifting (LP) and RFID as a logistical tool (ERP). We can say that the development of securing goods is not yet completed, but will made it harder the thieves to practice their craft.
