The main consequence of this was, of course, a fall in prices for the end consumer. Supermarkets, which offer many products for sale, usually benefit from the emergence of anti-theft barcode alarms. Indeed, small traders, selling fewer quantities than supermarkets, declined to implement the barcode alarms initially.
This was because they thought it was not profitable for them in the short term. Thus, supermarkets began to experience a particular boom at that time. Thanks to the barcode, this encouraged consumers to frequent these supermarkets to save time at the checkout. In addition, the smoother and more reliable checkout process makes the consumer and seller have more confidence.
The main purpose of anti-theft security sensors is to prevent shoplifting. Its technology prevents theft in real-time. But in addition to this main function, you can also use the technology to collect data on the flow of customers. Once everyone who enters and leaves a store passes through the EAS antennas, you can record and compare this movement.
Whether small or large scale, the barcode is the most efficient and reliable method of managing inventory. Indeed, if you want to manage your inventory in the best possible way, the barcode stands as the best option. The use of this method allows an automated, very precise, and fast-tracking of stocks too.
Store alarms usually go off when someone tries to steal an item containing an anti-theft barcode or an unscanned barcode. Stores usually detect shoplifting by making use of the anti-theft barcode alarm. Who has never gone through the embarrassment of buying a product and still hearing the hiss of the anti-theft system? At that moment, you would say: I think the salesperson did not remove the sensor from the product!
This is common, and it happens as a security issue. Sometimes, this gives rise to a phobia of barcodes. Commercial establishments usually adopt such procedures to avoid possible damage resulting from theft, mainly clothes and shoes. Here, you can place devices on clothing and products to prevent theft. These are triggered by sensors that carry an antenna and a circuit. Vertical bars installed on the doors of the stores usually detect the code of these devices.
Next, the sensors emit electromagnetic waves. And when a person tries to pass a product through the door, the sensor on the product interacts with the waves. This, in turn, causes the alarm to sound. Some sensors are very small and have their circuit containing high-frequency waves, which reach about 8 MHz.
You can only deactivate these sensors at the checkout by equipment connected to the barcode reader when making payment. Thus, we can say that shops are always shielded by an invisible protective layer made of radio waves. The ink vials can be combined with standard RFID chips to provide an added level of protection. However, smaller stores often use ink tags alone to save on the cost of installing a detection system.
Certain types of specialty merchandise require their own customized security tag solution. For example, liquor bottle tags attach to the cap and set off an alarm when the cap is twisted open. Eyeglass security tags attach to the frame, usually at the temples or near the end of the earpieces.
The thin design of the tags allow them to stick onto the glasses without interfering with a customer's ability to try them on. Shackle tags can be used to secure the handles of briefcases and purses.
Without a detection system, security tags are useless. Detectors typically are placed on both sides of each of the store's exits. When the sensor passes the detectors, the alarm goes off. Walmart attaches security tags to high-value items such as electronics, batteries, clothing, furniture, jewelry, make-up, and desirable home accessories.
Thieves are most likely to target profitable items and therefore receive the most protection. Walmart tends to leave lesser valued items such as candy bars, toilet paper, and unloaded gift cards as they will not incur a significant loss to Walmart should they be stolen. On rare occasions, store associates may miss a tag, leaving it attached to purchased items.
Make sure you have your receipt ready to prove the purchase of each item. RFID tags are often located near the barcode, which will set the alarm off. Additionally, Walmart undertakes stock checks which highlight unauthorized missing items.

Security tags are often attached to high-value items such as electronics, clothes, and selected make-up and must be deactivated by the cashier.
