On Swift’s 1989 Tour that is criss-crossing the globe, concert-goers receive a wristband upon entrance to the venue. At some point during the show it magically lights up, coordinated to songs from the queen of pop music.
What’s really going on here? As this Slate article explains, its powered by a company named PixMob, which specializes in wireless LED technology. The wristbands use infrared transmitters to control the LEDs on the wristbands (that’s the same infrared that’s used by remote controls to change the channel on your cable box). The PixMob LEDs can also be controlled by RFIDs.
Check out Swift’s concert in Detroit from this summer to see the bracelets in action. Here’s another video that shows the bracelets changing colors.

IoT is all around us.
