Use two fingers to put in your PIN

One actually presses, the other one doesn't

You could generate an absurd amount of possible PINs that could work on your card, giving any PIN peepers a seriously hard time, should they somehow have the intent to get ahold of your card and PIN through spying and pickpocketing

Safes, doors, etc. same principle

Even better tip: commit your false finger movements to muscle memory so not even a recurring stalker can bypass it

This will be totally overboard, and totally unnecessary, most of the time. But like any kind of security, it's good to have it even if you hopefully never need it

you can hold your other hand over while typing. I know the numbers and dont have to look, thats how I do it.

Thermal camera will reveal the buttons your fingers lingered on and in roughly what order as they cool.

Easily defended against: Upon finishing your transaction, simply press every single button on the machine in quick succession, with roughly equal firmness.

What if I use something else to press the buttons with one hand and covering with the other hand?

That's why I spend a few minutes afterward licking the keypad to lay false heat signatures and promote faster cooling due to saliva. Attackers/observers are temporarily stunned with confusion and disgust, giving me a brief window to escape unnoticed.

The ol' two-finger entry method. It's been around longer than PINs.

My method is to put four fingers over the four digits, and keep them in place while moving all of them for each press.

Assuming a four-digit code, your method generates 2^4^=16 possibilities; mine generates 4^4^=256.

Solid idea, I might try that actually

I prefer calling it "two in the PIN".

I usually speak very loudly while entering my PIN, "1 2 3 4"

Two fingers one pin

I've got the same combination on my luggage!

my pin is 12 digits, I could say it out loud and no one would still be able to get in

Making sure that machine is warmed up for whatever deposit or withdrawal you had in mind?

Do people not use fingerprint? Doesn't just make it harder, but eliminates the peeping aspect altogether.

Is it 1111 1111 1111?

Also dissolves some of the oils your hand left behind, which any 2 bit criminal with a forensics lab would pick up on in a second

Shit Not any more!

That is simple, but very good, advice.

How do you use a fingerprint to enter a pin?

Something that is potentially helpful for stuff like this:

Every nuneric keypad ive eever seen is laid out in the same way and therr is usually a little bump over 5 which is the middle number.

If you can orient yourself by touch with the bump then the numbers will always be in thr same place and you can use this trick and cover the pad with your hand to be extra discrete.

Its really not hard. Like. Blind people can function in the world.

If you're in the US or plan to go there, don't use biometrics for your phone. "Law enforcement" can't make you give up your pin, but they can take your biometrics.

1 1 1 1 1 1 1 1 1 1 1 2, then?

You can do the same on a keyboard. Use your left hand to lightly tap the 1234 keys while actually typing out the characters with your right. Saved me when I had to sit next to some nosy kid once.

My bank limits me to 4 digits, saying it "technically fulfills" the card supplier's security standards. I guess fake keypads are a bigger risk than people standing behind you, but still. Then again, 6 digits, which is the maximum, wouldn't change much, either.

Fingerprint, then pin.

Two in the PIN, one in the PUK

I learned to use the numpad by touch in high school typing class.

Still probably the most useful class I took in high school

Sometimes I'll do like jazz hand fingers on the keypad so it looks like I'm just jamming a bunch of random numbers.

Or I'll mimic something like this but without actually pressing the buttons

One of the keypad locks I have on my door requires you press two random numbers after your pin, which I always thought was pretty clever. The one my parents have rotates the numbers, which also works but is reallllly not compatible with being drunk.

Two fingers are ok, but I like to throw in a pinkie just to spice things up.

Did you learn that from the game Splinter Cell? I remember using that trick, I feel like the odds of it working reliably IRL are extremely low though and also requires a thermal camera.

I try to avoid the PUK...but I generally use my CAC for PIV.

I have both, sure, but if I scan my print, I don't have to put the pattern in.

Oh, yeah, trust — I do not intend to travel to the US in my lifetime again. Last time was in 2011.

You don't?

ChatGPT suggest a secure 12 digit password for me, please.

Somebody, maybe a youtuber, demo'd it on a checkout, maybe at a Target. I can definitely see fingerprints with my thermal camera, even after brief touches, and there's phones now with built-in thermal cams. You do need a pretty cool and uniform temperature keypad, so not one with electronics close behind it, and you have to image the keypad pretty close due to low resolution and pretty soon after the victim leaves - waiting for a receipt would normalize the temps. So, yeah, not a very practical attack.

But I feel like this whole thread is topic is pretty high on the improbable and unrealistic scale.

How shocking.

I use my penis as a stylus for optimal security--no way the casual viewer can actually see it in person.

My workmate used to do this 30 years ago.

I started copying him - same funny fake password - when I moved on. Then I left that job after 8 years. I came back to that crew 10 years after that, to where most of them had moved en masse after a calamity, and my casual workmate from back then was doing it a decade later -- same funny fake password. I laughed so hard.

Not a casual, no, but us trained competitive penis enjoyers can catch every stroke with ease

This post is about a pin for your debit card not your cellphone

I have whooshed and I am sorry.

Thank you.

Lol all good!!!!! But yeah, facial id or fingerprint on the phone for sure haha

😁🫆

We had very different experiences in typing classes. My teacher would regularly show up drunk (it was my first class of the day, so he was likely drinking until early morning hours), and eventually we just got all our instruction from his student teacher.

Actually, reading op again it's really unclear. I also thought of putting in a pin into mobile.

(Yes I noticed the word card in there)

Most card readers I've used in recent years have touch screens.

This is pretty much the norm now.

Thank you that made me laugh out loud 😁!
