This is good for a couple of reasons. The more obvious is that your viewing experience will no longer be obstructed by all your greasy fingerprints, so you don’t need to whip out that buffing cloth every few minutes. The second is that it might be good for touchscreen security passwords, especially when it comes to the “pattern” lockscreen on Android devices. It ain’t perfect, but it’s something.

To be fair, 3M isn’t saying that these screen protectors prevent fingerprint smudges completely. Instead, as the name implies, the fingerprints fade away on their own over time, so you may still see more a few smudges. In any case, the scratch-resistant screen protectors retail for $24.95 and should ship in a number of sizes.
