14.2.4.1 Physically Secure Your Device You may want to set u p a “find my device” service on your phone through a trustworthy entity like Apple or Google so you have a way of using their technologies to find and remotely lock your device if you lose it. 14.2.4.2 Avoid Using Bluetooth to Communicate Sensitive Information If you choose to use Bluetooth to transfer sensitive information from your device to another device, consider encrypting your files first. 14.2.4.3 Turning Off Bluetooth Discoverable Mode  Ensure you turn off Bluetooth discoverable modes after pairing a new peripheral with your device.  Once paired, you do not need to have discoverable mode on because your device will already know the peripheral’s unique identifying code.  This will also secure your device from any unwanted pairing attempts.

Near Field Communication Overview

Bluetooth and Wi-Fi while like near field communication on the surface, do have distinct differences.

All three allow wireless communication and data exchange between digital devices like smartphones. Yet near field communication uses electromagnetic radio fields while technologies such as Bluetooth and Wi Fi focus on radio transmissions instead. 370

Near field communication, or NFC for short, is an offshoot of radio-frequency identification (RFID) with the exception that NFC is designed for use by devices within close proximity to each other.  Devices using NFC may be active or passive. A passive device, such as an NFC tag, holds information that other devices can read but does not read any information itself. Think of a passive device as a sign on a wall. Others can read the information, but the sign itself does nothing except send the info to authorized devices. 371  Active devices can read information and send it. An active NFC device, like a smartphone, would not only be able to collect information from NFC tags, but it would also be able to exchange information with other compatible phones or devices and could even alter the information on the NFC tag if authorized to make such changes.
