Why The RF Hard Tag Dealers In Kolkata Is Gaining So Much Popularity Among The Anti-theft Systems?

The Radio Frequency anti-shoplifting system is getting very popular these days. This is because of the accuracy of the RF systems. Before we go into the details of RF hard tags supplied by the Retail Anti Theft System dealers in Kolkata, it will be better to describe the Radio-frequency system. The anti shoplifting alarms can now use the RF technology very effectively for various uses. We will further describe the use of RF hard tags as supplied by the RF Hard tag dealers in Kolkata.

How Radio Frequency or RF works:

The Radio Frequency or the RF system works much like radar which uses a transmitter and a receiver. The Radio waves transmitted by the transmitter can be placed near the exit doorway of a shop. The radio waves can bounce off the people who are walking past the doorways and further it can be reflected back to the receiver. However, the problem here is that it will reflect the radio waves for all persons passing through the exit doorway and will lead to a false alarm which will cause much embarrassment to the customers. This will fail to identify a shoplifter correctly. The ant shoplifting RF hard tags which are supplied by the Library RFID in Kolkata have been able to crack this problem very effectively. Apart from using a transmitter and a receiver, this system uses a concealed RF tag in the merchandises or the book store or libraries and in several other applications. These RF tags can only be removed by using some special type of tool. These tags are concealed so cleverly that it is very hard to spot these tags. There are other types of RF hard tags which are visible clearly and which may warn you and alert the shoplifter against stealing.

The coiled metal type of antenna which is embedded in the hard RF tags supplied by the EAS System dealers in Kolkata will pick p the radio waves emitted by the transmitter as somebody tries to pass the exit gateway without paying for some purchased items. The label will generate a tiny current and will transmit a radio signal having a very specific type of frequency. The receiver which is hidden and normally located in the door gate will further pick up the radio signal transmitted by the tag and will set an alarm. However, when the payment is made for the item, the checkout assistant will ensure that the item is passed through a deactivating device. This device will effectively deactivate the embedded electrical components in the RF hard tags supplied by the Sensor gate dealers in Kolkata. Thus, there will be no alarm as the customers pass the exit gate.

The uses of RF Hard tags:

The RF Hard tags are mainly used for the EAS system. These RF tags will only raise an alarm when something is being stolen irrespective of the type of thing being stolen. This is because all RF Hard tags will be exactly same. Apart from its use in the merchandise store, the RF Hard tags are also extensively used in libraries for identifying stealing of books from a library. There are a lot of other uses in RF tags being explored in the medical system and the future for the RF hard tags supplied by the Barcode Scanner dealers in Kolkata is going to be very bright.
