At present, there are ATMs near bank outlets and major shopping malls. In some of these areas, mobile phone signal jammer are installed and used. What's the matter? Do you need mobile phone signal interference in the area of ATM automatic deposit and withdrawal machines?

In fact, this is a kind-hearted technical guarantee measure taken by the management department of the bank against the illegal means of some illegal personnel: a low-power mobile phone signal jammer is installed near the ATM automatic deposit and withdrawal machine, and the mobile phone signal interference is only carried out for a small area in front of the ATM withdrawal machine. There are two purposes: one is to prevent customers from being remotely guided by mobile phones during deposit and withdrawal, The second is to prevent the wireless signal transmitting equipment from secretly photographing and recording near the equipment from transmitting the video or photos input by the customer's password to the outside, resulting in the leakage of the withdrawal password.

Some customers, especially middle-aged and elderly customers, are easily induced by telecom fraud. They often transfer their deposits to the other party's designated account through ATM automatic deposit machine step by step in the process of telephone guidance of fraudsters. When there is a mobile phone signal jammer near the equipment, they can interrupt the fraudster's communication at the last step of deposit and transfer, So as to win customers a certain amount of reflection and timely stop loss time.

Similarly, some criminals will use candid photographing and recording equipment to candidly photograph the process of entering passwords when customers deposit and withdraw money, and the mobile phone signal jammer will timely prevent these candid photographing processes, so as to improve the security in the process of deposit and withdrawal.

In addition, it should be reminded that ATM automatic deposit and withdrawal equipment is generally located in areas with dense population flow. Therefore, it is recommended that the transmission power of the mobile phone signal jammer installed should not be too large, otherwise the interference range of the mobile phone signal jammer is likely to extend too much, and the normal communication of ordinary merchants nearby should be avoided.
