Mobile jammer prevents transfer fraud

Have you heard of cell phone jammer? The phone is blocked from communication. It is an out-of-service device used to prevent signal transmission between the mobile phone and the base station. It causes strong interference to the communication between the sender and the receiver. Effectively block the transmission of 3G, CDMA, GSM, PHS and other signals. I cannot make or receive calls. It can cause more problems than improper use. Everyone in these industries is convinced.

The rapid spread of mobile phones is making a major contribution. However, invasion of privacy is a potential problem. Smart phones are often used in places such as subways, libraries, concerts, and movie theaters. Many people do not observe good manners. Cause a lot of trouble to the other party. Therefore, it is necessary to take measures. At this time, we will start operating mobile jammer devices that are out of service. This is effective. This device is an effective means of following good manners. We recommend anti-nuisance devices here.

In fact, it is not only suitable for university entrance examinations, but also for qualification examinations, high school entrance examinations, national entrance examinations, etc. This means that cheating using mobile phones has been discovered one after another. I think this method of installing mobile jammers and temporarily “stopping service” test sites is the most effective measure. A radio station license is required to install the equipment. By transmitting a weak radio wave of the same frequency as the radio wave of the notification message from the mobile base station, communication is blocked, and subsequent location registration and polling cannot be performed, so the display of the mobile terminal becomes “out of service area”. Communication is suppressed . We will also introduce this device around the bank. We will start to restrict the use of mobile phones at ATM corners. This is a joint effort by financial institutions to prevent criminal damages such as wire fraud. Multiple financial institutions will jointly install equipment at ATM corners. It is used as a measure to prevent transfer fraud.
