Should someone tell the folks at fraunhofer that they are a bit late?
There is a link to a 2013 smart ring article as well, but this just seems like they republished a press release without any real details as to why this is interesting, good or unusual.
Also, the rings are 125Khz–aren’t current contactless payment terminals 13.56Mhz?
Longer frequency? If they mean longer wavelengths then that’s wrong… if they mean lower frequency then that’s wrong too. They just wrong.
The best part though if the only comment on the article hahaha!
