"Password May Be Stored in Your Shirt Cuff"

Researchers at the University of Washington are working to improve upon smart fabrics with the use of magnetized textiles to store small amounts of data. The data stored on magnetized textiles can be read by a magnetometer, which could allow users to replace passwords or key cards with smart fabrics. This article further discusses developments in connected fabrics as well as demonstrations conducted by researchers on how data is encoded on smart fabric, and how it can be read.
