We had some dicussions with the Shell team. Currently seeing if we can have some synergies.
Def, it would be great to get Satochip compatible with the Shell device.
It is great to hear you already had talks with Keycard team!
Since software for all your products is basically open source, I see good reasons for this to happen.
Please keep us updated if anything changes in good direction, I am interested in testing this myself.
