Is there any possibility to get the number from the mobile sim card using any sensor ??? For example, if a person have a mobile phone in her hand and when the person pass from the gate we want to get the number of that sim card whose in her mobile phone!
Not possible!! You cannot get the number directly from the Simcard chip. The encrypted data and some other data!
