Track of tags!

EAS is a technology commonly used to prevent shoplifting from retail stores. In the application of this technology, specialised tags are attached to merchandise which cannot be removed by hand and require a specific tool. Also when this is put to use, a detection system is installed at the exit of the store which raises an alarm when it senses active tags being taken out of the store. These tags are attached to merchandise at the suppliers end and not at the store level. Known as source tagging as this originates at the sourcing end.
 
Deterrent against shop lifting
EAS systems are effective ways of keeping a check on theft. A shoplifter unfamiliar with these systems and their operation might either get caught or will cease from stealing. However, there can be a situation where a shoplifter familiar with the technique might be able to remove or deactivate the tags but the certainty is not hundred per cent in this case. A detacher is used to remove the tags and the type of detacher to be used depends on the type of tag atached. 

False Alarms
A major concern with these systems is when a false alarm is triggered. If a customer is walking around in your store with non activated tags, at times this can create false alarms annoying the customers and causing embarrassment to the retailer. To avoid such a situation the retailer should ensure that the employees deactivate the tags properly. 


Shielding
An informed shopper who is familiar with these technologies can surpass the surveillance check in your store by carrying merchandise in a bag lined with aluminum foil. The aluminum foil creates a Faraday cage which makes shielding possible. But some systems are programmed in such a way which cannot be beaten, however 30 layers of standard 20µm foil, will defeat all standard systems. The amount of shielding required depends on the system, the distance, its sensitivity and orientation of the tags with relation to its antennas. 

These electronic surveillance systems emit electromagnetic waves which can interfere with the working of other electronics and can, at times, have a harmful effect on the health of an individual. 

While this technology can be really beneficial for your store, you will also require traditional surveillance to keep the shoplifters at bay!
