I am happy to say that I'm finally done with the hardware design of the URU Key device.
I was some time since the last update on my URU Key project. However, the project did not stop, no.
While working on the side project URU Card [/tag/uru-card/] - the open-source authenticator device in the form-factor of a regular credit card - I have noticed that it is way more suitable for daily use. The device like this can be carried around simply in the wallet together with other credit cards. So, I have redesigned the URU Key in this format.
