Back to the story, this Encoder Ring can basically store up to 64 characters using binary numbers.
It’s still a concept but I think it can go well if a company decides to go into production with it. (Similar to Tokyo Flash binary watches)
Encoder Rings began as an investigation in how to store precious or personal digital information. The result is
a series of rings that are decorated with tiny blobs and holes, that actually represent letters in binary code; the
code used as the basis for digital information. The user would choose a secret message 64 characters long,
have the message translated into binary code and finally have a ring produced using rapid-prototyping.
