The Quiet Tag: How RFID Started and Sketched a Connected World

Added: 2026-05-07

[00:00:00]RFID story starts with early radar ideas in Mario Cardullo's 1973 [music] patent for a passive wireless tag.

[00:00:08]Engineers wrestled with power, read range, and backscatter, testing coil geometries while skeptics [music] doubted a tag that could hold data.

[00:00:16]Its impact grew slowly as access control, [music] livestock tracking, and logistics adopted wireless labels in everyday life.

[00:00:24]Decades of refinement [music] sharpened antennas and memory, turning bulky prototypes into slim chips in phones, shelves, and transport [music] hubs.

[00:00:33]Today, RFID binds objects to networks, from warehouses to libraries, a quiet revolution beneath our connected world.
