Google, The Jewelry Designer

 Google is in the process of designing a security device to replace written passwords for authenticating user access to computer devices according to MIT Technology Review.  Rings and other  jewelry designs are being experimented with to hold security information.

Here's a YouTube video that demonstrates how diamond laser inscription technology works:
