DEF CON 28 Badge Hacking

This tweet is apparently directed at the lanyard:

Google translate yields:

Korea is divided into north and south. They speak the same language and have the same customs. And, it's the same people. It must be peacefully unified. To do that, we need to have a conversation with each other. That is the way to live. “I love each other”

Possible the top halves of the lanyard need to in fact be AND/OR/XOR/something'd.

The l (elle) was in fact an upper case I (eye)

What's up people!
I believe I solved the transcribed text from cassette case it's a keyed Vigenere Cipher
Key is : "NOMATTERWHEREYOUGOTHEREYOUARE"
Decoded text is as follows "Know that as in life there is much that many have looked upon but few have seen because as my father told me and his father told him you will come to learn a great deal if you study the insignificant in depth "
