Keeping a Bluetooth device in 'discoverable' mode allows any other gadget with Bluetooth capabilities to search for and locate it within a certain range. Because Bluetooth devices are to some degree traceable, the concept of Bluetooth surveillance has been introduced into the tech world. Security has long been an issue with this technology - bluejacking, for instance, although simply a harmless prank, allows Bluetooth users to send out unsolicited messages to nearby devices. In fact, it's the very nature of Bluetooth - a technology that can search for and locate other devices that also have Bluetooth - which has some people concerned. Such a thing is possible, and it's happened before. Having fun shopping?' Sounds like something out of a movie, right? As you linger in front of a shoe store and consider a new pair, your phone beeps: Someone's sent you a text message. This allows other Bluetooth phones to locate you. Maybe you're just doing some casual window shopping, and you've kept your phone with you and left Bluetooth on 'discoverable' mode. Imagine taking a walk through a crowded area - perhaps the shopping district of a big city. Wireless technology seems like it's everywhere these days. It uses Bluetooth technology to alert users if they spend 15 minutes or more within 6 feet of another user who subsequently tests positive for the disease. This phone displays the COVID-19 contact tracing app, launched by Britain's National Health Service.
