Fingerprint scanners... and brothers.
My brother just bought a Yoga 520 i5 laptop which has a touchscreen, and also a fingerprint scanner just below the keyboard. It's actually a very nice laptop.
Anyway, after he'd had it for a day he brought it round to me so I could finish setting it all up and I enquired if he'd set up the fingerprint scanner.
Brother: "No, I couldn't get it to work".
Me: "Why not, did you put your finger on the scanner?"
At this point I pointed at the anonymous looking fingerprint scanner below the keyboard.
Brother: "That's the fingerprint scanner? I spent an hour yesterday touching my bl**dy finger on the screen...!"
Oh how I laughed. Hahahaha. Families. I swear he's not related to me, there must have been a mix-up at the hospital. Yep, that's got to be it.
