Q: How can I keep someone from stealing the info on my smartphone?
A: If someone is scanning your devices to capture information, depending upon the device, it can gather the information and format it in a way to use it later. So, if there are multiple account numbers that it is accessing, it can grab and store them separately. Since it is a machine, it may be hard for the machine to decipher legitimate information from invalid information or to parse information effectively for reuse. This is why we recommend: (1) turn Bluetooth discovery to off when not in use or secure your settings and (2) to avoid using "free" wifi when in public locations to avoid someone scooping up your information.
