Heads up: it looks like they have the expiration date embedded in the first barcode and one of the pictured reagents is expired. Have you been able to set the system clock?
I'm aware of the expiration date, but haven't been able to understand the embedding or how the pairs of codes may be "hash validated" in some way, which means that this is a one time use for me unless I can either generate them or access the nvram on the system.
Any insights? How did you find the embedding?
Generating a new barcode and sticking it on top of the old one shouldn't be a problem, though?
