Selinko Authentication Cards - NOT WORKING.
Posted by Maker Gillian on Nov 1st 2026
The Selinko Authentication Cards and the Gillian Knives App have stopped working. I don't know why.
I don't maintain the app, or blockchain. I only maintain the data on the cards and rely upon the Belgium company Selinko to make everything work on the platform.
I have been made aware of the problem that the cards are not working. I have attempt1ed to contact Selikno multiple times via email, but have not recieved a response, other than the annual invoice for maintaince. Which I paid in full July of 2026. I have learned that Selikno was acquired by TOPPAN (a major Japanese printing and security tech firm). This might have caused a temporary disruption of the app, platform, and support. I have not recieved any response from Selinko or TOPPAN Group. As of now the FAMOCO device that programs the cards is working, but the apps and cards are not working.
