Can iBeacon scan iOS devices even bluetooth is off?

Question

iBeacon/sensor tags should scan the devices that enters my store and report some information to the server/device. Information like device name, what position and how much time customer spent at particular product. My questions are:

1. Can iBeacons scan the device(IOS bluetooth smart ready devices) even if bluetooth is switched off?

2. If not, what should replacement i have to use for it.

Answer 1

If the Bluetooth is off then how can the iBeacon even see the device. So no this is not possible. And no you can not see the device any other way, wel maybe with some GSM/WiFi detector but you will never be able to the device name or something.

Also the iBeacon is transmitting an identifier that the users device is picking up, so I don't think you iBeacon will be able to to detect any device since the protocol should then work the other way around.
