How to tell uSD cards apart.

[maven]

Is there anyway to tell uSD cards between the Solus Ultra and the MODIS Ultra apart?
A friends shop just hired a new kid, kid decided he wanted the shops software in his scan tool. My friend stopped him before the kid actually swapped cards but now he doesn't know which is which.

Anyway to ID them? Which machine is less likely to brick with the wrong card installed?

put the cards in a card reader and view the file contents on a PC, maybe even shop stream connect. I wouldn't think there be any scope files saved if the card belongs to the Solus, see what cars were worked on with each
