- bee_rider 3y agoThat is interesting. I’m sure it depends on the application to some extent. I can type my pin in without looking at all, so I can cover it up while doing it. If I had to hunt and peck, it’d easier for an onlooker to observe my slower motions I think. But if I used the same machine often enough to produce wear specific to me, this randomization would be really useful.
- zootboy 3y agoI use a randomized PIN pad on my phone, and I've gotten quite used to it. I can enter my PIN almost as fast as I could on an unscrambled pad; it's definitely not hunting and pecking.
- 8note 3y agoDo they randomize the key locations though? Otherwise, you leave behind grease where your fingers touched
- segfaultbuserr 3y agoYes, the layout is randomized every time you use it.
