Consumer electronics designers seem to favor low- or no-contrast markings, with this USB reader falling on the vanishing end of the spectrum:

I poke the MicroSD card from the AS30V helmet camera into the smaller slot on the top surface, but, contrary to what’s revealed by the camera’s flash, the slot is a black-on-black target.
Well, I finally fixed that:

Although white tape surely would have sufficed, the roll of fluorescent red came to hand and that’s what it’ll be. The CompactFlash and Memory Stick slots on the front don’t see much traffic and have better access.
I slapped tape on case, trimmed the slots with a razor knife, and declared victory.
Much better!
