Cell phone jammer have become a necessity of modern life and become a useful society. This tends to inconvenience people around them. In hotels, coffee shops may disrupt business. Radio stations operating communication jammers are licensed and allowed to run. As much as possible in order to prevent "fraud fraud" approach, and in advance to prevent damage, we will install a device, in order to prevent the call in ATM corner. The phone number of the people in the shop had no influence.
