Bluetooth signals tend to be unreliable, bouncing off different surfaces and creating echoes, which means that the app can record radically different distances between two users, even over a short period of time. Thanks to Google and Apple's new API, the app's algorithm can now take this into account when trying to establish how far two handsets are from each other, using statistics to narrow in on where a contact actually is. … [Read more...] about NHS contact-tracing app upgrade is more likely to warn users to self-isolate

Other schools rely on Bluetooth beacons and campus WiFi networks to track students around campus, as The Washington Post reported last year. The data not only thoroughly tracks students and compares their behavior to "norms" generated by peers in their cohorts but also may be used for grading and attendance purposes.

This can be especially important when crossing international borders. It only works on light sources outside the frame: If you’re taking photos directly in sun- or a floodlight, you’re still going to get lens flare.
