The scanner that monitored the main entry of the military detention center on Coruscant accessed the coded information contained in the insignia squares affixed to the left breast of Krennic's tunic, and with a chirp of approval the thick door pocketed itself into the partition, allowing him to pass.

I'm finally reading Catalyst and what, the rank plaque badges contain coded information? I didn't know that. I love that. I'm waay behind on reading/watching Star Wars content, and haven't seen this mentioned anywhere else. Does anyone else have this? Or is it just Catalyst Krennic?
