This may be an obvious question but are there differences between the vivokey spark and flex other than the form factor?
not an obvious question at all.
The Spark is an AES128 cryptobionic implant that works with the VivoKey service platform. Both the Spark and platform have not had much in the way of information put out there yet, so it’s not obvious at all and the question is absolutely warranted.
The Flex One will also work with the VivoKey service platform (via applet deployment), but also it can autonomously run java card applets published on the Fidesmo app store.
